I thought of this idea while using the Variable mod. I made a mining minigame where you mine ore then smelt it then make coins with it, now do mine the ore I selected OnActivate. So now it looks like your are hitting the brick with your hand. To give it a more realistic feel I think someone should make some "Fake" tools. They do activate the brick, but the item doesn't do what the item was originally for. So for my mining mod, A fake hammer would do nicely, you could hit the brick to mine with the hammer, without deleting them.
