lol, my first thought when I saw this, it reminded me of an old "board" game I got from Value Village that me and the kids still enjoy playing: "Avalanche" (it was from the 1960s, I think )

more info: http://www.weddslist.com/avalanche/index.html -- and hey look a Java implementation "The marbles never get jammed in the gates" aw but that was half the fun!

PS: "Despair.com" + Board Games = punny stuff!

The urge to build this is very strong!
