I've got a rotating tesseract demo up on CodePen[1]. At least, I think its a rotating tesseract - I have no idea if it's an accurate representation because tesseracts lead me into thinking about quaternions and then my brain shuts down.

Thanks! I took your code and modified a bit to remind me of what I had saved years ago. Not quite right but closer.

Careful around complex numbers!

BTW poetically enough, codepen has a tesseract for a logo.
