Robocom: a game for programmers 14 years ago
Hi, I'm the guy who invented RoboCom back in 97. Yes, RoboCom Workshop is Windows only (unfortunately), but there is a compatible interpreter named RoboTour which has been ported to various OS. It's not at fancy as RoboCom Workshop but it basically does the same.
The most exciting news about RoboCom is that I have started to re-write RoboCom as a web application in pure JavaScript (actually CoffeeScript). It runs in any modern web browser. The compiler and the simulator core both somewhat work, but it's very early alpha. The thing is that I have currently no time to continue the development because I founded a company which keeps me super-busy... but expect it to happen some day :)
