The author also created SpaceChem, which is one of the best programming/engineering games out there. For just programming games, I'd call it my second all time favorite just behind Robot Odyssey, an ancient Apple ][ game.

This gives some great context to where SpaceChem came from. Thanks Zach!

I thought I recognized the favicon! He's also the guy behind Infiniminer (the primary inspiration for Minecraft) and KOHCTPYKTOP (a game where you design basic digital circuits that I'd like to personally thank him for, for expanding my mind beyond the "pure" software realm: Thanks, Zach!)

SpaceChem is included in the current Humble Bundle, with still 10 hours remaining, FWIW.

Sweet! Thanks for the tip. looks like EFF just got another donation for $6.54 USD, and thank you Zach for donating your software for charity!
