Vector Smears (Take 1)

As a side project, I decided to look into doing algorithmic smear effects. Smears are done in older cartoons, mostly because transparency is difficult when using paint. There's an imgur album full of stuff regarding this topic, you should go check it out first.

As a concept, smears are made by making parts of a body appear to be at different points in time, and that point in time is generally based on what's closest to the "front" of the motion and what's closest to the "rear" of the motion. Using this concept, I've built a simple prototype:

Path:

Smear (1x):

Smear (2x):

Smear (3x):

Smear (5x):

Smear (10x):

Smear (25x):

It would seem that my algorithm needs a little work, although it's not too far off. I just need to take into account volumetric smearing next.
