Neat idea! Not sure how you'd do with a Kickstarter on something like this. Suppose if your goal was low enough to just get started and essentially it would be like taking pre-orders, you'd at least get an idea and if you didn't hit your goal then no harm done.
Gauging product interest here on Pinside is "hit-and-miss".. I have yet to put something up that people go ape over. One thing I've noticed is that if it has leds that strobe a ton of colors, you'll have a few hundred customers in no time
