My ignitors work. This is 2πr, a fire arts project that we took to burning man last year with some amount of it working. Last year the ignition system consisted of two blowtorch heads per effect (16 total). This year I made the Juniper system. It is so much more solid.
So 2πr is a motion controlled fire art peice. We are sitting on a podium, and just triggering all of the effects for testing, but the podium has these little blue and red lights, those are the motion sensors that trigger the effects along the perimeter. There are videos from burning man last year, but it's one of those things that doesn't video well.
