I'm sure this has been mentioned before, but a quick 15 second search couldn't find it.
I am looking at doing LEDs in a couple machines, and have already gone through a couple. I find I'm scouring pics of pins looking for lighting ideas on titles.
It'd be really cool of there was a way for pinsiders to document the lighting schemes they've put together. Start with a pf map and allow users to specify lighting for each.
