Remember that marriage proposal that popped up on Google Maps? A more effortless and streamlined way of conveying a message has arrived in the form of GeoGreetings. The creator must be an avid fan of Google Maps, where he gathered images of buildings that looked like letters to put together the Geogreeting. Enter your message, and let the engine do all the work of locating the letters all around the world. You can then forward a link with the animated message to your friends. That's impressive!
