Mindstorm EV3

MSRP $349.99 The Mindstorm Ev3 is something to behold. Sure it only adds up to a measly 600 pieces, but it takes on several forms, has its own infrared sensors, it has a programmable brick that you can use to make your build move and speak, and the build can be commanded with your tablet or smart phone. This is the Lego kit of the future.
