Goggles - The Google Maps flight simulator. What a brilliant fucking idea! Take Google Maps. Add a cool little plane. Incorporate into flash. Distribute for free for all to play with.
Sure, the flight screen could be a little bigger and it would be nice to be able to incorporate into Google Earth, but none-the-less, this is still great. Oh, and I'd like to be able to fly a little higher too sometimes. I know, I'm picky. I should just appreciate what a good idea this is.
