The thinkfun series is also awesome - http://www.thinkfun.com/learn-coding/ http://www.thinkfun.com/learn-coding/ Appears related to lightbot, but it's closer to cellular automata - where the robot has a state that determines its next step. It's played using cards, which feels more fun strangely. My 10yr old loved it.
