Well, this is kind of amazing: someone has created the game of Knokkers, which is an insane combo of billiards and bowling.
You see, you play on a gigantic pool table that you stand on, and all the balls are the size of bowling balls. I think you see where this is going.
Created by Steve Wienecke, the game's rules are pretty much just like standard pool, except you can pick up the cue ball (once you touch it, you can't move, however). So, who wants to build a Knokkers court in their back yard?
