I made Cubiverse for such a thing.. (Score 1)

Hey, I wrote the Web based game crafting system Cubiverse for bridging the gap between voxel style games (Minecraft, etc.) and "real programming". Basically Cubiverse gives you the ability to create cube worlds, but add Javascript to control them - you can make lift, teleport players, control the time of day, spawn items, etc.. Having said that it's still very much in BETA but I'm keen on hearing opinions on what to do :) Check it out at http://www.cubiverse.net/ James
