LUA + Minecraft Mod + Cluster Computing = ?

Hey guys. So I know that this topic is VERY unrelated to Java, but it is at the same time because of the fact that Minecraft and Minecraft mods are coded in java. Anyway, if you play Minecraft, you MAY know of a mod called ComputerCraft. If you do, great, if not, I will quickly explain. ComputerCraft adds fully programmable computers to Minecraft. The language they are coded in is LUA. You can code practically anything with them. There are also things that allow you to connect computers together - modems… and network cables. There is wireless but it is short range and I prefer wired. Anyway, I want to create a “supercomputer” from many computers connected together with network cables. Now, I understand the complexity of this, but I have plenty of time to kill every day, so its on. Now, My question to you is, WHAT should I make this supercomputer do? I have considered things like Prime95(GIMPS) and calculating PI, but those bore me a little bit and due to memory, are somewhat limited. I intend to create something SIMILAR to folding@home but about a trillion times simpler. It would be … interesting … if someone coded folding@home and I could use it with the computers, since they have HTTP access to the real internet, but it would be too complicated. So anyway, if anyone has any idea, tips, or suggestions, PLEASE let me know! Thank you for your time!
