I want this sirpinsky triangle ! This is so tatisfaying

Click bait. This is all trivial and the geometry showed in the thumbnail is not even here. Dislike and move on.

the largest possible imgainary sphere is the tricylinder steinmetz solid.

what about the thumbnail?

Thumbnail problem - My answer is a cone with an infinitely thin square wall in the middle.

It's a chicken nugget

I feel like that one guy in Idiocracy

These shapes all go in the square hole.

I KNOW THE SHAPE FROM THE THUMBNAIL ITS A GUITAR AND ITS MUSIC WAS ELECTRIC

an imaginary sphere is an imaginary cube just in a sphere shape

it's like 1am, my first thought is that that might be interesting for crystallography.

Wow

First i came to thia video thinking it would be just a challenge video to guess shapes, but it turned out to be something a lot better, "i came here looking for Cooper but i ended with gold instead"

Amazing video! One interesting note is that the right rule on a fraction x can be stated as x+1. And the left rule has a similarly concise statement: x || 1, where "||" is the "parallel combination" operator, famously used in electric circuit analysis to find the total resistance of two resistors in parallel. By extension, m consecutive right moves can be stated as x + m, and m consecutive left moves as x || (1/m).

Looks like witchcraft 😂😂

Me thinking this was just a simple game: 🤡

Now just add another shadow

2:30 actually these shadows are wrong, (two of them should be stairs shaped like [][][] [][][] [][][]

There is a video game just about that called Viewpoint

5:40 Maybe the latin squares work because since each row and column have all the numbers, which means there isn't a gap on the shadows.

you could do the same process you did to the cube as the sphere i think, just imagine the sphere being in a cube

Another imaginary cube is an octahedron and the octahedron can be a fractal but it can’t possibly use cubes to make it

He never returned

Potato: I am shape 🥔

Very nice video :D

The initial picture i saw was basically the tip of a flathead.

Woah it's good a

You expected a cube, but it was me! The Sierpiński pyramid!

now for the imginary sphere pls

Damn. I was three months sober from fractals. I just wanted to watch an innocent video about shadows and finite shapes, and you just had to bring up fractals.

So, what's the answer of the thumbnail?

It’s a cylinder!

I do think that the serpinskis pyramid fractal making the square shadows is cool but something that I’m curious about is if it physically could make three perpendicular square shadows because from what I gathered, it’s shadow only makes a square when the light source is looking straight at the edge of the shape, but since none of the edges are perpendicular to eachother, I don’t think the serpinskis pyramid would actually be a solution to the 3 square shadow question (this is assuming that the light sources in the posed question are perpendicular to eachother). I may be wrong though and if I am I’d greatly appreciate if someone could correct me

This is tingling my autoCAD days.

Man, I woulda watched this sooner if the thumbnail was more accurate to the content. This was really good! That said, I do understand the grind.

If thats not a 7D spheroid from hell thats bull. 0:50

Brilliant work

I got the second one wrong, but called it a circular prism

This reminds me a lot of the illusion created by making 3D shapes that appear to say one word from a certain angle, and a different word from another angle. I believe those are constructed using Boolean geometry, usually, by creating the letters of one word in 3D and then subtracting the negative space of the letters of the other word from the shapes at a 90 degree angle.

dude i was here for the quiz :(

Oh... clickbait. 🤦

I literally figured this out with out watching the vid. i'd say that the q on the thumbnail is easy

when I saw the thumbnail I yelled peanut

This video has instantly become one of my favorite videos on the website. It's been a long time since I've ever been so baffled by something so simply complex. Love it, hope there's more in the future!

This video popped up after I had an after thought on my calculus classes last year about projections and parametrizations. And I do believe it would be such an interesting excercise just to go around doing the projection of random irregular objects

If 3D fractals can make square shadows… then is a Klein Bottle a three dimensional shadow of something arbitrarily more complex in the fourth dimension? My brain is hurting thinking of what fourth dimensional fractals would look like…

whatever it is, it fits in the square whole.

7:38 oh com on that joke was so *shady*
