Arduino (Score 5, Interesting)

Seems to me like you can do an awful lot with the Arduino platform. I recommend buying from the Make guys, as you'll also see that they've published a book recently with the Arduino developers/creators that maybe your kid would like as a follow-on? They are only $30.00 and the only requirement is a computer to plug the thing into for programming. I'm asking my wife for one :-).
