The modern age has a new twist, called the Bridge Design Contest: download the software, design a bridge, and simulate it. The strongest computation wins, just like a video game. No wonder bridges fall down. It has something to do with babies and bath water.
See the latest high school scoreboard.
If you would like to participate, "teams can have no more than two members." Get started at http://bridgecontest.org/enter/how-to-enter/.
