For anyone who has an iOS device: download the FREE "Tiny Tower" app game. It is really fun, and highly addictive. Instead of destroying (as in "Angry Birds"), you build the lives of tenants in a building complex. Choose what kind of floor you want, let out suites to people, hire them, fire them, move them around, and bring in the customers. Apparently you can build up to 100 floors of stuff. It continues to run in the background, but you need to keep an eye on it because if you run out of stock, the customers don't come!
