Bebot is heaps good.

It is used by Dreamtheater.

Would be cool in class.

Some website has this to say!

//Touching the screen causes the robot to move and make sounds controlled by your movements. Play it like a musical instrument, or just have fun watching the robot and making sounds with your fingers.// //Features 4-finger multitouch polyphony, multiple synthesis modes, user-definable presets and scales, tweakable synth settings and effects, and more!//

Bebot could be used to teach students about synthesisers and scales.
