Placeable Goat Horns

This small mod transforms goat horns into decorative blocks that can be placed in the Minecraft world. The most interesting part is that these blocks can transmit sound signals! When you connect several horns with redstone dust in a straight line, sound travels from one end of the chain to the other.
