Is the cube a fully static model? Or is it 2 parts?

Yes it does, I ... had a lot of work on it and at some point I figured there was no point to make more details.

Also that cube is made of 2 parts, the outer shell spins at different speeds across the 3 axis, and the center always is static, which makes for an interesting effect.

Do what ye can. It's not like doing a prop for a movie, where it has to be done! (But let's not get into Ed Wood territory)

Hmm that's good. Usually something inside of thing would be fully one object. Is that kind of thing easy to program?

Calling it "programming" is a bit much said. I just made an animation. I set myself a span of like... 360 frames, and on the final frame, I ordered different rotations depending on the axis:
X: 360
Y: 720
Z: 1080

This way this thing makes rotations across all sides and returns to its default position in the end, although that was slightly tricky as animations like this are non-linear by default, that means that there's an acceleration effect, while this certainly needed a linear movement at a constant speed. I got it to work, but I can't help but be slightly irritated that in this case, things are like this, but in Adobe Premiere, where I'd prefer things to be non-linear, linear is the default
