These scripts let you generate arcs with any number of control points. Examples inside.
Recommended that you use the YYC. Should work on any platform (only using draw_line() functions, no external dlls or anything like that).
Requires lots of processing. Works best with YYC. In the hair example, I could get 60fps on my machine using the YYC with 256+ individual "hairs." On the normal windows compiler (soon to be deprecated) I could only achieve 10 fps. Lots and lots of math. Please keep this in mind.

UPDATE: Now supports drawing under the curve (with configurable colors, transparency, and even quality of the line!).
*Can now color under the curve/line. *Can set quality and other properties such as colors for lines.
