Kevin Serafini introducing Google Sky Map
John's new SkyMap application for Android does stuff that you're not going to get your iPhone to do because of hardware, rather than software, limitations. It makes use of the phone's GPS, accelerometer, and compass to create a window in the sky that moves with your hand.
John Taylor's demo at Google's Searchology Event
John and I actually had a discussion way back when about using the iPhone's GPS to simulate the G1's compass. The iPhone knows your position, so if you walk for a small distance in the direction you're facing, it should be to able to work that out as well...
Of course the question we couldn't resolve was "how far" in the direction you're facing you'd have to go, and in the end we figured it probably wouldn't work all that well. Just one of the reasons I'm looking forward to WWDC, which for once I'm actually going to be at, and the possibility of getting my hands on some new iPhone hardware.

Well done John, very cool. Now, how do I get my hands on a G1 again?
