Wow, didn't know about that. It sounds quite similar to the more recent "electrostatic halftoning" algorithm by Weickert et al, that apparently does not cite your work:
I'm trying to figure out whether this is a compliment, a criticism, or both. When topics related to 2D graphics come up, there's a fair chance I've done some relevant work in the area. I plan to continue shamelessly hawking my results, as that's an important part of a research pipeline :)
