I suppose I'm interested in it due to my huge appreciation of my iPhone and have come across a few different articles about multi-touch (using two hands in natural movements) touchscreen technology and one of it's innovators, Jeff Han.
This 2007 Fast Company Magazine article on Han was the first I heard about the technology (now fairly well-known on the "magic walls" used by various news organizations to show election projections.
Then in May 2008, the BusinessWeek article "A Touch of Genius" overviews the technology and then Time Magazine profiled Han as one of it's "100 Most Influential People".
Fascinating stuff both from the perspective of the technology out there right now and what's to come...
