It's alright, but it suffers from one thing...the lack of ability to register a "hold", as it seems to be entirely motion-activated. That, and I don't know how spot-on the timing can be with it. But it can be fun.
As far as the product as a whole...I love it to death when I got people over, but it doesn't have enough to it to keep me occupied while alone. I'll say this: it has potential.
Heh, also, I've been thinking...from the shots of "Groove" I saw a few months ago, I wonder if it'd be possible to somehow suspend the camera from the ceiling (facing down at you) and have it almost be like Para Para.
