Basic Projective Geometry.

Neat to watch thanks.. fun to see short illustrations like this.

One of my favourites would be the one entitled "Moebius Transformations Revealed" (guess it's not entirely unrelated to projective geometry :)

Anyhow - cheers for the video.

See Wiki : search Mobius strip.  Mobius trip is more to do with topology and the "real projective plane" in geometry.
