I wrote a Lua based programming game more than 10 years ago. You can look at it here: http://infon.dividuum.de/ http://infon.dividuum.de/. Source code is also available on github: https://github.com/dividuum/infon https://github.com/dividuum/infon. It was used during multiple local hacker conferences to keep the guests entertained. For that you would run the server somewhere, then run multiple viewers all over the place (and a big central screen) so everyone could follow the current game. Players would then connect to the server through telnet and upload their Lua code. Code could be updated while the game was running so people kept tweaking their code all the time. It was really fun seeing more than 20 player competing. The game should still work today and is basically feature complete.
