Yesterday I downloaded the Bridge Construction Set simulation game, free from Apple’s web site, and haven’t put it down since. You build a bridge and then test it with real physics. Bridges are constructed however you want and then tested to see if they fall into the river or if they support animated cars, which delightfully crash into the river if your design is too creative.

It’s easy to use, although unfamiliar when you first view it. Here’s what I wish I knew:
1) Use the “edit” mode to create a bridge and “simulate” mode to test it.
2) In edit mode, click a circle on the road to insert a link and then click where the end of that piece goes.
3) Command-click a circle to delete a link.
4) In simulate mode the red pieces need help.

Oh no! I didn’t put enough cables in, my train’s gonna fall in the river with splash sounds and everything.
