LegoEngineering.com is having a free online class next month.  The class will deal with the programming aspects of the NXT-A-Sketch robot.  The robot is very simple (basicly just two motors mounted to the NXT Brick)  however the programming behind it is quite complex.  The class is beign taught using NXT-G and will use a variety of the more complex blocks to write the program.  Looks like a great introduction to some of the more advanced NXT-G topics, and although its free registration is limited.  Check it out over at LegoEngineering.com.
