Poorly compared to what?

Sorry for not being clear, in a more "objective" sense of reproducing the original image as a stacked series of polygons in this case.

I realize that that is only sort of the point (there's a lot of "cool technique demo" here).

Wow - 2009. Excellent post. I recently entered a competition (February 2013) and used this technique without having seen this blog. I also used webworkers and SVG.

btw, the original article about using Genetic Algorithms to derive Mona Lisa's image also generated quite a bit of interesting discussions here, 4 years ago:
