I wonder if you can constrain the problem a bit more: say, limit the number of triangles that can be used; limit the color palette to a small set of colors. It would make for interesting results.

You can already limit the number of triangles (points) used.

And you can limit the palette as postprocessing in any image editor. I can't see much reason why you'd want to build that into this tool.
