Hit-the-pin

You take a couple of pins, a very heavy ball (don't kick it, trust me) with holes in it (but there isn't getting any air out, so they stay round.. it'sa magic). And then you throw/roll/move said ball across some sort off ballroom floor towards said pins.
Object is to make them fall.

Some points of notice:
* Maybe they should make the sides of the ballroom floor a bit higher: the current set-up allows the ball to roll along the side, so the player misses all the pins.
* The pins aren't set up real good domino style: if you hit the first, they don't fall down all together.

ps: love the see-trough ball effect :)
