With 16 red LEDs, thicker plexiglass, and a mat, it looks much better and brighter.
Much better results

OK, so there are still some problems left. But this is exciting anyway.
It's in a frame!

This image has 12k points. I don't think this many points are practical on the mill, but it looks pretty good onscreen. Screenshot from the stippler software, resized and cropped with gimp.
Stippling with lots of points

(3500 points)
Stippler with variable-sized dots

This uses the formula 1 + density * 4 / max_density which looked better than the "correct" version with sqrt. It remains to be seen how well this effect can be seen when hole-depth is varied.

A few weeks ago, I stumbled over a paper by Adrian Secord describing an algorithm to turn a greyscale image into stipples. Here are the results of my implementation of his algorithm. UPDATE: I added the original photo of Marie, as well as the version that was used as input by stippler.
