#2Wow, the title does not make it justice: I only went to look at it in an idle moment after lunch. Much better to transcribe the beginning of the video:
4D Toys is a toy box filled with 4-dimensional toys.
By 4-dimensional I mean that they exist in a world with 4 dimensions of space and 1 dimension of time, instead of 3 dimensions of space and 1 dimension of time.
It turns out that the rules of how objects bounce, slide and roll around can be generalized to higher dimensions, and this unique toy lets you experience what that would look like.

#3There was an indie game that had 4D puzzles (as in actual 3D + time), and the person/team behind the game developed a framework and map editor to work with those properly...
I cannot recall the name, but it looked awesomely complex!

Was the game Miegakure [0]? It has the same author as this paper/post, and pretty much seems to be the premiere 4D game. The parent link says that the research shown here was developed for Miegakure, so it might be the game you're thinking of.

Sadly, it might be one of games with longest development..

#73-manifolds have some pretty great descriptions to https://blogs.scientificamerican.com/roots-of-unity/a-few-of...
Bill Thurstons Three-Dimensional Geometry and Topology is a great read

#8If you like this, then checkout the presentation on Geometric Algebra from 2019 SIGGRAPH: https://www.youtube.com/watch?v=tX4H_ctggYo
You can then play around with objects in 3D, 4D, and beyond:

#9I'll ask any physicists out there. A 4th spatial dimension probably doesn't exist, right?
Even if we couldn't perceive shapes across a 4th dimension, we would still perceive things moving through the 4th dimension like we see in 4D toys. In reality we don't ever see anything like this (spatially anyway). Is that correct?

#10I would like to see the 4th dimension projected into 3d and not just a slide, same as you could project the 3d into 2d, by showing further objects smaller and closer objects bigger.
