Saw a photo of a guy with an iPad hanging around his neck Flave-style. Got me thinking how much fun it would be to have an app that displayed a landscape video image of an Xray of a human chest showing heart beating. Other options could be Alien-like creatures crawling around, stuff going down the esophaugus, and so on. Great gag potential if hung or held in front of chest. Call it "xRay for iPad". Any other goofy app requests?
