love google sky map awesome app.
" Layar " is another insane app. Its free Download it from android market you can do a youtube search to watch a demo. Its totally crazy it combines your camera & gps with the internet and icons appear on your screen as you pan round with the camera it shows the direction of these places/events. The options are virtually endless, search for fast food places nearby, pubs, clubs , theatre, golf courses, play virtual games, search upcoming events, wikipedia , google search intergration. Bonkers mate im still playing with it to see what else it can do.
