Minecraft: Self-Building Bridge

Using the piston mod, I was able to create a mechanism that would automatically generate a bridge with the dimensions specified by obsidian. There is a bit of a bug in the current version of the mod that can sometimes break pistons, but otherwise the bridge will automatically start repairing itself when any part of it breaks!
