I'm haven't dumped dozens of hours into a game in years, but I just blew ~10 hours and lots of sleep on this one: Desktop Tower Defense. Super addicting, and waaay too easy to get started. :) After a hundred attempts I finally beat hard mode tonight, with a score of 6589 and only 4 lives lost. Phew! Now I never have to play this game again!
I wrote the CLAB well converter today. It's pretty cool. :)
I presented the ChemChains sandbox at the Omaha Dynamic Language Users Group on Tuesday. What could possibly be more fun than boolean networks?
