Isn't that what the traditional 3d visualization of a hypercube is? e.g. https://en.m.wikipedia.org/wiki/Hypercube#/media/File%3AHype...
It gets weird because our eyes see almost in 2d, and even with VR, there is a 2d feed to each eye that gets combined to add slight 3d depth perception. So really we would be projecting a 4d world onto two 2d plains that our visual cortex would try to merge to add slight depth perception.
