Built a giant creeper head, Â*it's 31x31x31 blocks which doesnt sound like much but it's pretty big. First I wanted to be able to change the eyes to lava, but since lava makes adjacent wool blocks (from which the whole creeper is built) burn, I changed it to torches. All black parts can be pushed and pulled by pistons, when they are pushed the black wool blocks block the light, if not the creeper head will be enlightened! This can be operated by a lever which is at quite a distance from the head, to make it look better. The redstone to the lever has been covered up by sandstone.
