I was an early backer of the original chibitronics.com/ Kickstarter, and a fan of the "electronic stickers" philosophy.
And I've long wondered whether it would be possible to extend these from doing just LEDs into being used with sound.
I wonder if there's a way to make a kit of conductive tape + LED stickers + sensors + the right kind of connectors, so that you could make your own fun touch panels for use with AE Modular.
The idea would be that you got, say, a piece of hard board that fitted an AE Rack. That had the right patchwire inputs / bus connections. But hooked up to something that afforded conductive tape connections. Then people could build their controller by sticking tape, sensor stickers and LED stickers.
It would be fun for kids, or people who wanted to give their AE Modular a more "folky" custom look. A combination of modular geekery with craft / scrapbooking etc culture.
