The Lego NXT Pinball machine, built by Mark Gryn of the School of Computer Science, University of Windsor and Michael, an 11th grade student who is participating in a co-op program at the University of Windsor is pretty impressive creation. It uses 6 NXT's, 9 touch sensors, 10 light sensors and 4 motors along with over 8000 LEGO bricks!
Read the full story here, where you can download instructions, NXT-G program and learn among other things that, (and I quote) "The inspiration for this Lego NXT Pinball machine came from a machine built by Gerrit Bronsveld & Martijn Boogaarts. Their machine was built back in 2005 using the old version of the Lego robots known as RCX."
