Geek Gifts 2011: The Unofficial LEGO Mindstorms NXT 2.0 Inventor's Guide

GPS blocks would be great too...
And a variety of sensors... imagine if you could build a set of mindstorms drones to seek out rogue wireless devices!!! It's not so far off, you know.

I highly recommend the well-organized and exciting Inventor's Guide to anyone wanting to get started with this hobby, or to be given as a gift along with the set to provide the necessary knowledge to get the most out of the NXT 2.0 set.
