Anybody seen something like this for the Diamond?

I was just browsing phone junk when I came across this link http://dailymobile.se/2008/02/28/3561/ I thought it was an interesting concept I am sure someone way smarter than me has already dove into this but this would beat the snot out of Apple's gestures.

Anyway just thought I would share and see what other people thought.
