About me I've been a computer programmer since I first started typing in program listings on a Commodore Vic 20 when I was about 8. My hobbies include electronics, CNC manufacturing, photography, beer and winemaking.
I live with my wife and lots of left-over parts from unfinished projects in Lincoln, Nebraska, USA.]

With 16 red LEDs, thicker plexiglass, and a mat, it looks much better and brighter.
23 February 2005, 3:03 UTCIt's in a frame!
OK, so there are still some problems left. But this is exciting anyway.22 February 2005, 13:57 UTCStippling with lots of points
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.21 February 2005, 17:13 UTCStippler with variable-sized dots
(3500 points)
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.
17 February 2005, 3:37 UTCStippler: Turning photos into dots
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.
