Vector Smears (Take 2)

So after a little bit more work, I've managed to get the smear effect to look a bit better. It still needs a little work, but I'm getting really close now.

Smear (30fps)

Smear (4fps)

I need to figure out how to make the artifacts that occur when the shape flips inside-out stop happening. My best bet is to figure out which points in time the velocity of the object changes dramatically enough to cause such a problem. I'll need to do more testing.
