I am in awe of this LEGO Technic Difference Engine, a scaled down but fully functional version of Babbage’s Difference Engine built entirely out of LEGO. Besides being an amazing feat of LEGO engineering, the web page itself has a great description of the Difference Engine and how it computes. Absolutely wonderful!
Did you see the Wired story on Lego 2.0? It’s a good read.
Oh – very nice. I hadn’t read that article yet. I also just saw the link to the Art of the Brick gallery at http://www.nathanbrickartist.com/gallery.html which is very impressive, but unfortunately seems to be down right now.
