Just code up a lemmy plugin that lets you embed basic interaction for navigating 4D shapes, my dude. It's just basic eigenvectors.

They were being a smart ass.

You must be fun at parties

There are 2D monitors though.

You can project a 3d object into 2d space and you can do the same with 4d into 3d, but collapsing more than that generally loses too much information. Edit: If you include movement you can reduce this effect somewhat depending what you're doing.

Your portrait is now just a colored line the height of your subject, and this "4D cube" doesn't mean anything because it looks like a 3d cube with a smaller cube cut out of the middle of it. Unless you're really into geometry I guess it you dropped a /s.
