O2 Stare Out
I just found this new site on Adverblog and its really interesting. Using a webcam you line up your eyes with your chosen rugby player and then stare out against a video clip of the player doing the same. You can also submit your winning time and details along with a snapshot of you staring to a winners list. I imagine the site looks for changes in the shape and colours of the eye area to determine whether you blinked or not. Worth a look.
