Sorry, I just mean floating blocks -- blocks that you've just mined but haven't yet picked up. I call them "hoverblocks". We could even pretend they're really weak "mobs" that do nothing except sit there and rotate. If you get near them they "jump" at you, die, and give you one block of material. If you wait and don't touch them they die on their own. (-:
