Interesting. What I've been working on is casting a flat image on an irregular surface, so that when viewed from a specific angle, the visual data compiles back into the original flat image. The obvious limitation, depending on how you look at it (no pun intended) being that you have to view it from that specific angle. Now, I don't know about moving images, but I suppose I could attempt maybe three fixed images viewed from three distinct vantage points, cast on one 3-D object. (I'll leave it to your imagination what specific object I'm using as a "canvas" here...)

Julian Beever has done some interesting 3-D sidewalk drawings with chalk, like:


and



Here's another good one:



Keep in mind that these are all 2D, and only look right from one angle.
