On a more serious note:
Develop a video system for the slopes that you can trigger, ski through, then look at at the bottom. A more advance system could be set up for a Ski Instuctor to do a movement analysis. This might be a money making setup for a mountain. It could be done with electronic sensors and mostly automated equipment.
Put a buck in, make the run, get the video downloaded to you via the internet.
Think about setting these up for half pipes, kickers, "terrain features", etc. An automated NASTAR system that records your run. The ideas are endless. People would pay good money for a record of their ski trip that they could send to others.
