Description
I know this is just a demo so it's probably not that important.
When I played around with the triangulated lines demo I quickly produced ugly slivers.
It happens whenever you move the snake in one direction and then reverse the direction.
Mere self-intersection (snake bites its tail) doesn't cause it unless the circle is too small.

Research direction
Start by running the triangulated lines demo and reproduce the slivers by moving the snake in one direction, then reversing it. Trace the demo's line triangulation and self-intersection handling; done means reversing direction no longer produces the reported ugly slivers while ordinary self-intersections remain correct.
