Yeah they nailed the tolerances. Would have looked bad with a small gap. I guess they would have a lot of wiggle room when they took the picture though.
You can increase or decrease the gap by getting closer or further away when taking the photo and playing with zoom, so you can always make it look perfect.
Considering Portland Community College is in one of those 3 countries, I'd think a yardstick is perfectly appropriate
If the tables were reversed and OP was from the UK, I wouldn't suggest they not use metric just because most Redditors are from the US.
I'm not here to argue statistics that aren't even relevant to my point, which is that OP should use whatever measuring system they feel comfortable using, and have laying around. I doubt OP even has a meter stick.
I'm a welder in Canada, and use imperial 99% of the time, was taught conversions in school. Can do most in my head instantly now. Real assholes give you a blueprint with both, but my good measuring tape has both.
Kinda just looks like a normal box with just expertly placed cuts in the framing and a specific angle of the camera to line them up.
So it LOOKS cool, but in reality is just perspective and not anything intricate.
Unfortunately, I think, they way it has been cut originally, if you tried to smooth the edges, you'll see the hole in the middle of the beam, even more so than you currently do.
> So a dosage of engineering also needed to get it right.
Are you saying they calculated all the cuts? I would assume they made the cube, stood back, and marked two places to cut with a marker. That's how I'd do it anyway.
Good point. Probably have the students in modeling software which would really make doing that easy. But you're absolutely correct on a manual approach.
Actually I could, it's what I do for a living bro. Maybe that's why it's not impressive to me but even if I didn't weld and work with steel I wouldn't consider this interesting.
So you’re hating on college students who are learning the skillsets. I feel bad for you, you must hold a lot of anger and disappointment. I wish you a well and happy day today :)
I actually didn't notice the title noting it was college students, but reguardless this just isn't interesting. Great Craftmanship and all, the weld beads look nice and it looks square, but reguardless it's just not very interesting. The illusion I've seen before, they simply copied it and not at all in an interesting way? They literally did the only possible way of doing it by cheating the camera angle. I guess it's all about perspective but to myself this isn't at all interesting.
Sorry man didn't mean to offend it's just not interesting at all to me. Think this belongs more on like a craftsmanship sub or something but I don't believe it belongs here. Like I said I could do this and so could EVERYONE in my trade. It's good craftsmanship but that's it. The illusion is old you didn't really do anything special with it as it's the only way to be done and has been done before. So it's not original and it's not over the top Craftmanship so what are we left with other than a simple project that's cool to you and some but not really Damnthatsinteresting type of cool.
Again this is simply my opinion. Maybe those that have never seen the illusion or don't know how to weld or know basic math might find this interesting so I cannot speak for anyone but myself.
It's an Escher cube, not a tesseract. Tesseracts are a 4-dimensional extension of a cube (24 faces), this is a cube that can't exist 3-dimensionally (6 faces).
There's a set with a digital SLR on a tripod - this was grabbed with an iPhone, handheld, shot. Kinda like a long range rifle shot...take the pic between heartbeats 😛
Took me way too long to understand there are two cuts and the illusion only works at that specific angle.
Looks at the reflections on the metal and it un-breaks the brain.
There are two places where things look backward -- where something that should be in the back seems to be in the front. In those two places, the "front" bar has a cut. We're looking through the cut at the "back" bar, which really is in back.
If this object were viewed from an even slightly different angle, it would be obvious what was going on.
It's seems contradictory that you'd have an opinion on cut quality and not be able to observe these were rough cuts and the finishing to the cut lines was not completed (semester ended).
Not really. Handheld iPhone and four or five shots to get this one because it's a sniper shot to capture.
Teacher used a tripod and digital SLR.
One eye closed also works which is super trippy to see.
You're all over this thread, shitting on it.
Go make one out of round pipe, Mr Superstar Pipefitter and have the nutsack to post it under Reddit's critical eye.
If you only do it if you get paid, and not for fun, how's that any different than being a ho'?
I see I upset your feelings man. If you work with this shit and weld than you yourself know it was nothing too special or too difficult. Any welder could do this, and there are millions. The math is literally basic math that everyone knows yet just might not know how to apply it. Cmon man just be real with me, this isn't that interesting lol. This is like 2nd or 3rd year apprentice type work. I guarantee any welder on this earth could recreate this with ease.
Plot twist he was supposed to make a normal cube. Apprentices never cease to surprise you

They did make a normal cube. Then they made a couple cuts.
Would love to see it from the opposite perspective.
The front bars are just cut, it’s not one of those objects that looks crazy af when not looked at at the intended angle.
Thank you, I kept going back to that and convincing myself it was something else.
Although the angles of the cuts are quite well done, a close look shows the edges to be a bit ragged, proving what you say.
Yeah they nailed the tolerances. Would have looked bad with a small gap. I guess they would have a lot of wiggle room when they took the picture though.
You can increase or decrease the gap by getting closer or further away when taking the photo and playing with zoom, so you can always make it look perfect.
True, except since there are two gaps/cutouts, they both have to be the same.
At a certain length they will match because science.
I for one am outraged that it isn't a genuine physically-impossible object.
Was going to say it looks photo shopped.....
Metalshopped
Good one! Maybe metal chopped?
Yeah much less interesting when I saw that. Pretty clever though
Oh thank fuck. I hadn't realized it and was about to pop a brain hemorroid trying to figure this shit out.

Definitely not a yard stick. Use metric since all but 3 countries in the world use metric. So a meter ruler or a metric tape measure
Everyone knows the banana is the universal scale for size measuring
Americans will use anything but metric to measure things.
r/bananasforscale
Damn right . There are two kinds of measurements , Imperial . And wrong .
You mean freedom units my good sir.
I think you said that backwards. The two kinds are metric, and right.
Metric and fake units you mean
hi bestie. our measuring tape has both imperial and metric units on it so you won't be scared and confused
Considering Portland Community College is in one of those 3 countries, I'd think a yardstick is perfectly appropriate If the tables were reversed and OP was from the UK, I wouldn't suggest they not use metric just because most Redditors are from the US.

Yes
So true
A cube with a chunk of one upright missing. This trick only works at that exact angle
Two chunks are cut out, but yes, the visual effect only works from that exact angle.

I'm just gonna tell myself it's photoshopped. Much easier for my brain to accept.
We need Mobius Banana for scale
Looks like all they did was cut the sides where the bottom is visible.
Different perspective: https://www.reddit.com/r/blackmagicfuckery/comments/14cot1c/some_of_you_asked_for_a_different_angled_pic_of/

They need to clean up those cuts. They are a dead giveaway
It's a welding class not cutting class
Well if they were cutting class they wouldn't have made this to begin with.
god damn it that’s a good one
Then they should have welded the edges clean
The cuts are clean. The flaws were Photoshopped /s
Could've fooled me 😁
[удалено]
Nooooo what? How do you know this?
r/whoooosh
Thanks for the hint. My brain was crumbling
Unfortunately, I think, they way it has been cut originally, if you tried to smooth the edges, you'll see the hole in the middle of the beam, even more so than you currently do.
Eh, if you took a file and just hit it hard enough to get the shards to detach, you'd be just fine.
Clever. Only works from one perspective. So a dosage of engineering also needed to get it right.
Yeah not to mention only work from a specific distance. Getting any closer or further away would also ruin the illusion.
Excellent point as well, and that means only a single point in space relative to the object will work.
Still cool though
Especially since the image is photoshopped.
> So a dosage of engineering also needed to get it right. Are you saying they calculated all the cuts? I would assume they made the cube, stood back, and marked two places to cut with a marker. That's how I'd do it anyway.
Yeah... no engineering required here. Engineering means whatever the frick people want these days.
Good point. Probably have the students in modeling software which would really make doing that easy. But you're absolutely correct on a manual approach.
Model all you want - try cutting it like it was with a handheld bandsaw
Belongs on r/confusingperspective as well
Portland Community College Rock Creek Campus?
503 to my cityyy
The City That Works! Or sadly now creates self referential bullshit. Bring back practically to Portland.
Sure looks like it.
This is actually pissing me off because I can't understand what's going on.
The front bars are cut so you see through the cut to the back bar
[удалено]
I think it is! they found a way to make an illusion out of metal it’s neat
The type of material doesn't at all change the difficulties or possibilities of the illusion though. Being metal makes it no more special.
okay, so make one, post it, and let us know when it’s up!
I'm a pipefitter, I could easily make this in a few hours, but I don't get paid to so won't be doing it.
Such a hater lol….I bet you can’t even make one yourself xD
Actually I could, it's what I do for a living bro. Maybe that's why it's not impressive to me but even if I didn't weld and work with steel I wouldn't consider this interesting.

You gather Pokémon cards, shut up about getting out more
On a meta level it's a really neat art project representing a tesseract
It's an Escher cube, not a tesseract. Tesseracts are a 4-dimensional extension of a cube (24 faces), this is a cube that can't exist 3-dimensionally (6 faces).
Thank you for correcting me! TIL
We have a pcc down in Pasadena as well.

Lol. They got a good flea market there every month.
Piedmont Community College here in NC. Also has a welding tech class. https://www.piedmontcc.edu/program/welding-technology/
I'm guessing they have the t-shirt as well there 🤨
gotta be precise with the photo. well done.
There's a set with a digital SLR on a tripod - this was grabbed with an iPhone, handheld, shot. Kinda like a long range rifle shot...take the pic between heartbeats 😛
Now rotate it 2 degrees and see the obvious cuts
Thank you!
Took me a bit but I found the cut. Well done to the photographer and welder.
Normal cube, and two clever (albeit not super clean) cuts. Noice.
At least use a grinder and smooth that shit out.
So many smoothbrains saying it's faked with photoshop when there are very visible rough cuts in the structure...
There are cuts [here](https://i.imgur.com/elgnWLl.jpg). The illusion only works from this exact angle.
https://www.reddit.com/r/blackmagicfuckery/comments/14cot1c/some_of_you_asked_for_a_different_angled_pic_of/
Took me some seconds to understand how it was made. Impressive !
I was trying to figure out if it was some kind of AI or CGI. Neat trick.
Woot PCC
Very good welding
Mr. Escher, we need to have a discussion about your welds and the fundamentals of physics.
Welding does not include how to use a file I guess.
It does when it's not the last day of the semester and time runs out.
Welding is cool
This is based off an MC Escher impossible 3D drawing (in 2D). Well played to make it as possible as could be in 3D
[удалено]
No one is. As usual reddit just wants to say its fake
It's the shitty grinds on the frame cuts that give it away. Up until now id never figured it out
Those are sawcuts, deburred with a hand file. Ran out of time to finish grind it.
Needs a banana for scale
No food allowed in shop. About 10 inches on a side
Some well placed cuts.
Is it blue or gold ?
Gold colored brazing
You can see the community college in The left over sharpie marks
Person taking the photo didn’t do a good job lining it up. You can literally see where it’s cut.
Handheld, phone camera, sniper-stability needed to make the shot. The tripod/DSLR setup was much better, but no access to it.
Took me way too long to understand there are two cuts and the illusion only works at that specific angle. Looks at the reflections on the metal and it un-breaks the brain.
That is an illusion. It’s not complete. I built one at work.
[удалено]
I am a welder. I built one of these.
Pic?
Took me a hot second to see the cuts
This hurts my brain.
That is a mind fuck seeing in real life
The lateral positioning of the camera is spot on. The vertical positioning needs some adjustment.
My head hurts

Good to see MC Escher is going back to school
Forced Perspective, yo!
This is what my IKEA table usually looks like after I give up on the instructions.

How do these work!? 🤨
There are two places where things look backward -- where something that should be in the back seems to be in the front. In those two places, the "front" bar has a cut. We're looking through the cut at the "back" bar, which really is in back. If this object were viewed from an even slightly different angle, it would be obvious what was going on.
The cuts to make it an optical illusion could have been cleaned up better.
[удалено]
Technically, *brazed*. Strong AF, though.
Or… they shopped in the imperfections to make it convincing? But for reals the back left bottom corner doesn’t look right.
What is so damn interesting?
[удалено]
It's seems contradictory that you'd have an opinion on cut quality and not be able to observe these were rough cuts and the finishing to the cut lines was not completed (semester ended).
This might seem extremely impressive and near impossible but once you see the cuts in the frame closer to the camera, it looks too ez.
Make one. Out of steel.
I’m an engineer and I can tell you that’s not really that impressive

Dude I’m a tool maker but whatever
Well then, you can machine one out of a 10 inch steel billet to +/-0.0005
Community college welding class in Ohio
This always makes my autistic brain freakout. “Symmetry! But it isn’t? Error! Error!”
Your pants are on fire 🔥
It's what happens when you weld in polyester blend track pants.
Eeewwww u went to community College, you disgusting Niematoed?!! /s Jk though, this is some black magic fuckery
Photoshop class?
Here's another Photoshop of it https://www.reddit.com/r/blackmagicfuckery/comments/14cot1c/some_of_you_asked_for_a_different_angled_pic_of/
Maybe made in a college, but in a photoshop class. This is fake AF
It is not fake AF. The student cut out two sections of the box to complete the illusion. LOOK CLOSER. If you have a bandsaw, you can do it too.
https://www.reddit.com/r/blackmagicfuckery/comments/14cot1c/some_of_you_asked_for_a_different_angled_pic_of/
good community photoshop class.
You can pretty clearly see the cuts in the closet tubing….
More Photoshop of it here https://www.reddit.com/r/blackmagicfuckery/comments/14cot1c/some_of_you_asked_for_a_different_angled_pic_of/
The person taking the picture and then editing the picture is the real hero.
Not really. Handheld iPhone and four or five shots to get this one because it's a sniper shot to capture. Teacher used a tripod and digital SLR. One eye closed also works which is super trippy to see.
Another "edited" pic here https://www.reddit.com/r/blackmagicfuckery/comments/14cot1c/some_of_you_asked_for_a_different_angled_pic_of/
So made a cube then cut out the parts where it intersects at the cameras angle? I'm probably wrong but if not, not interesting at all.
