davidoreilly.com — While working in 3d last year I discovered this optical illusion.A large grid seen rotating at a certain speed will appear to group itself into smaller grids, spinning independently. It appears the persistence of vision effect overrides our knowledge that this is a single grid and divides it up optically.

NathanielJ is correct. It's not persistence of vision; it's temporal aliasing.<a class="user" href="http://en.wikipedia.org/wiki/Temporal_aliasing">http://en.wikipedia.org/wiki/Temporal_aliasing</a>

I wish I could formulate thoughts with such clarity. In that case I wouldn't need our chef technological officer to translate to other programmers what I wonted to say during a meeting :)

How about "don't look at this if you have a migraine or headache"?

I believe the first time i noticed this effect was when I was playing f-zero for the SNES, perhaps it is why I liked the game so much!
