RFC Minecraft Server

by Ben Coman

I'm not ready to do this yet, but just surveying interest. I'm thinking of creating a Minecraft server using Pharo. My kids are enthusiastic about playing Minecraft and I think its a great platform to grow their creativity and cognitive skills per [1]. Much better than passively watching TV! [1] http://minemum.com/minecraft-educational I'm particularly interested in using Minecraft modding as a platform to teach programming to my kids. I had high hopes for the Scratch-like interface of learntomod.com, but I found it awkward and unsuitable. Other options for writing mods include Java[2], Javascript [3] or Lua[4][5]. For now I'll probably settle on Lua, but I'd prefer to be teaching them with Phratch and later directly with Pharo.
