Personally I am not very big on sites that use Flash. But sometimes you come across ones that really seem to catch your attention, well at least mine. As I was browsing the web (which happens to be my job), I came across upshot which is done in flash and is extremely entertaining. The whole site pretty much revolves around a ball that guides you throughout the site. If you get a chance, give it a go, I am sure you will enjoy watching the ball help you navigate
