Gee Steve, while an attractive idea, I don't know of conductive epoxies available with low enough resistance to attempt something like that - not that I've looked recently.It would be fun to use the larger 1206/1210 LEDs to go to town with conductive epoxy. You can get artistic and have it done in a day of 'painting'
