My spelling is pretty bad, and my cardio ability could also improve. Retronyms, an iphone application developer, has created the game to help make my spelling and cardio ability improve in both a fun and social way. The game uses GPS and satellite images to lay out a playing field filled with virtual letters for the player to pick up, think of a scrabble tile scavenger hunt. Watch the video to see how interesting and cool this might be. The program costs 99 cents. The Catch? You need friends with iphones.
