Admittedly, not all of this made intuitive sense to me at the first get-go and some of the interactions seemed like they required too much slow, deliberate movement (that may have just been a director's choice -- update: or its possible that this is just a conceptual mockup, i.e. fake), but an interesting take on how to port a Photoshop interface into a multitouch world. But I would be happy just to have a screen that big in the first place.
Update: eric dolecki on John Nack's blog points out that this may be a fake (i.e. concept mockup) as the UI sometimes leads the gesture.
