or would uLisp work? They list support for ATmega-based Arduino boards, which is what TinyCircuits use?

I saw your booth at Maker Faire last weekend and your boards looked amazing, but I've never worked with Aduino boards because I don't know C. Will your boards work with Cylon.js or Artoo? Would the tinyshields and displays be supported?
