The Dispensers+ mod adds 2 new dispensers. The user and the placer. The user shoots an item and when it impacts with a block, it is used
onto this block. (like when you right click on grass or saplings with bonemeal). You craft it like a normal dispenser, but with wood.
The placer shoots a block and when it impacts with a block that block is turned into the one that was shot. It's crafted like a dispenser,
but with stone bricks. For more information, pictures and the download, go here:
