Giant iPhone video is cool, but quite fake

This video is making the rounds lately -- on first glance, it looks someone running the iPhone OS on a Mac Pro with a 24" multitouch monitor. As you can see, everything more or less works as you'd expect, and therein lies the rub: anyone who's looked at it with a critical eye, including our friend and former TUAW-er CK Sample III, has pronounced it fake. I'd have to agree -- besides the fact that it comes from a visual effects house, the picture flipping at about :56 is a little bit off. How'd they do it? It's most likely just a movie running on a screen, with a guy pretending to control it. But even so, it's a compelling idea -- if you could find a multitouch monitor that worked like that and ran the iPhone OS with it, wouldn't it work exactly that way anyway?

I've actually brought up this idea before -- there is a ton of software running on the iPhone currently, and some of it is even better than the equivalent versions on the Mac. It would be extremely useful to port the iPhone's OS (and all of its software in the App Store) to another form, whether that be on your TV (I originally suggested a Wii-like interface) or on a multitouch input like this desktop. Apple has sunk a lot of work and design thought into this OS -- they may never do it, but it seems like it would be a terrific decision to bring some of that successful R&D back on to the TV or the desktop.
