Just in case you missed it, this week Google Maps was fully hooked up with Keyhole satellite photography.
I've been trying to stare through the windows of Guardian Towers to try and see what's going on, but no joy.
Actually, here's one where Multimap has the edge: their aerial photography is not quite as swish, but it is taken from directly above and has a nifty rollover map, so you can see what streets you're looking at/spying on.
