With zenphoton I really wanted to keep the user interaction model as simple as possible, since part of the 'zen' was in the drawing experience itself.

I made a more complex tool based on the same raytracing style, called High Quality Zen (HQZ). It has some support for representing curves as many small line segments with interpolated normals.
