That's really neat. Thankfully, I'm quite good at crossing my eyes like this, so I can see all the 3D.
Unfortunately, my Media player won't loop the animation, but that's not your fault obviously.

If you have the original frames, you may be interested in recreating the animation in the anaglyph style. This way, you could make it much bigger, and everyone could see it (at least those with the cheap 3D specs). My program Stereoptica would be good for this.
