I would like a logo, I think I've made enough slightly innovative things to not be a newb ;) (I made the first powder food that can be cooked in many ways and with multiple flavours, I believe)
Preferably, small, indestructable or easily destructable (if it will leave bits, then just make is indestructable) and with something moving (but not a spark that covers the whole thing, just a little spark would be perfect)
