Playing Jenga is exciting, so how about scaling things up? When those blocks drop in front of us, there's some kind of excitement we feel. But if these blocks drop, there's going to chaos. The reason? They weigh 600 pounds each.

This is not your regular Jenga. It is played by a team of five giant, agile, Cat excavators. You'll need some really skilled technicians to handle these machines and play this game.

The video below is clearly a promo for Cat, which is pretty epic too. Repositioning wood, after it is scaled up, seems to be no easy feat at all. [YouTube h/t Digg]
