Alternate to ‘Clicking’

Antimatter posted up an interesting link in the forums last night.  I got to play around with it for a while with a mouse, not a pen, but ended up clicking a couple of times…  The site portrays an environment where there aren’t any mouse ‘clicks’.  As I posted in the forums, I like the idea, but would it be possible to change the way millions of people are trained to interact with a computer???

Make sure and test it out with your pen and report back if you like the idea!
