Minecraft: Cool Mob Killing Machine

"Death Bowl" Mob Trap (Tutorial) by Monkeyfarm http://www.youtube.com/user/monkeyfarm

Pretty cool, this is not for farming or experience, but for fun & the look.

You don't use TNT in Minecraft for farming to often IMO ^_^

Be sure to check out Monkeyfarm's Youtube channel, he has a lot of Minecraft VOD's up.
