What you’re about to watch above is a video featuring a new functionality probably found in a new version of Sense UI running the HTC Hero with Android 2.1. It seems to be a multitouch feature where you would pinch-and-zoom (a la multitouch) to see all of your 7 homescreens. It works just like the Expose feature in Max OS X. Of course, this could also just be the masterpiece of a very clever and sneaky developer, and not an official ROM. My answer: watch it anyway.
