I looked at the ICFP Contest too. I didn't even get as far as solving the first problem, but I did implement a virtual machine that appeared to work. I really enjoyed the coding, though I didn't get very far with the physics! I tried a couple of approaches but settling on the functional side. Performance was not bad (from what I've seen it was vaguely comparable to the Python implementations, but was completely blown away by C/C++ implementations). I really wish I'd had the time to do a visualizer!
My code is on github too (http://github.com/fffej/ClojureProjects/tree/ 1494815e83febebe9af28b0cb08b812a63df9e96/icfp/uk/co/fatvat) and there's a write-up on my blog (http://www.fatvat.co.uk/2009/06/icfp- contest-this-time-its-functional.html). Again, I'd appreciate any guidance on anything that I could improve!
