### Re: 4-D cube!

Looks like a good prototype for a load carrying robot!  But where would one put the load?

hi mathgogocart

Yes, that is indeed cool!  Be nice to make an avatar out of it.

Well it's 4-D,   so 'on the inside' of course.  he he!

On which inside?

Imagine building a stage out of those!

There's only one inside on a hypercube.

### Re: 4-D cube!

It'd be easy to tell when you were inside.

When you can see 8 cubes surrounding you, you're on the inside.

Actually, you cannot exactly see cubes, but that's besides the point...

Maybe we could use a "Klein bottle" for the robot and put the load on the side.

Which side?

### Re: 4-D cube!

What's cool is that the side we're seeing in motion is really staying on the same part of the hypercube. It just looks like it's moving because of the limits of 3D space. Rotating in 4D has a weird effect on its 3D shadow. :3.

Hi stefy!

Inside/outside whatever we wish to call it.  A Klein bottle only has one side, right? (similar to a Moebius strip).

Have a quite blessed day!
