Cool Flight Sim/Bicycle integration

Carlton Reid has a YouTube video up at Quickrelease.tv of a guy demonstrating a bicycle being used to provide the controls to use the Google Earth flight simulator and fly around the world. Who needs a computrainer. I kinda hope that he figures out a way to turn the whole thing into a package that could be strapped to a spinning bike or bike in a trainer. I know when i'm at the gym, having something interesting to look at and pay attention too is pretty cool. I wonder if there is any other software out there that this could be wired to for "scenery". Like say, a bike stage route?
