....I did a similar thing, a little C program to generate an Eagle script=20 that added and placed 144 RGB LEDs. Fun to watch it run. Instant LED=20 panels. (well, except for the stuff that needed manual routing, i.e.=20 everything except the LEDs.) For examples showing high level sophistication in EDA, check out the=20 demos at altium.com. It is a whole nuther league above Eagle. Big boy=20 EDA. Cost is around $6K, but I haven't sprung for it yet.
