Okay, here's how you do it. You take one (1) bike, one (1) Google Earth Flight simulator (built in to the Google Earth download), and a lot of creativity , along with a used bike, and presto you are riding a virtual magic carpet exercise bike. The video shows the bike in action, and it looks like a hoot. The pedals control the power, the handlebars serve as the steering (logical) and a couple extra levers serve as the rudder and elevator (apparently). A SunSPOT, a 3d wireless controller that speaks java, serves as the connection to the PC. Put it all together and you have some fun.
