Something like that. It doesn't seem truly possible to render in actual 4D without everything looking like an absolute indecipherable clusterforget.
You'd need a 3D screen for that, I think. a 1D screen can give an illusion of 2D, a 2D screen an illusion of 3D, so you need a 3D screen to have an illusion of 4D.
And you wouldn't be able to see all of it, since we're not in 4D space.
Fun fact: In 3D space, you can see everything in a 2D plane, and in 4D space, you can see everything in 3D space. Fun, right?
