Non-euclidean geometry

[Enjay]

This kind of thing is available in a limited form simply with teleport lines too. There have been plenty of WADs released where the player climbs up inside a multi-story building. It seems to happen seamlessly but when you check the map, the floors are in different locations and you have teleported between them at some point where the teleport is as unnoticeable as possible.

The biggest give away is when sprites or decals disappear as you are moving from floor to floor...

Also still LOL'ing hard at Siggi's pic
