Rent a helmet cam: ontourHD or POV.1.5 helmet cam at the shop located next to the valley gondola station. A special CamTerminal is waiting for you to burn your runs on a DVD after you filmed each run with the helmet cam. The fees are 25 Euros for 4 hours and 40 Euros for the whole day. Not that much for having a unique souvenir to share with the whole world online later.
