You can see the double covering of the spin group on SO3. That allows a 720 degree rotation every 360 degree rotation of 3D space.

Pretty trippy (trippier still is that these things called spinors are a fundamental building block of reality)

Physics is p neat

EDIT: application is at 1 hour, 31 minutes, 46 seconds in case you dont open in a new window

I'll give it 1 bump before letting it die
