Someone made a modified version of Quake back in the day, that rendered to stereoscopic 3D in a white noise pattern.

It was such a mindfuck to play!

You get 3D depth but no colors or shades or contrast. It’s just shapes moving. So doors that were flush with the wall were impossible to see, but enemies in dark rooms were fully visible because there is no light or dark.

I like to imagine I got to experience what a bat sees with echolocation.
