Not sure if this is even possible, but I'm looking for an iPad app (perferably a clock) that will come to the foreground after a period of time and then move to the background after either touching the screen or tapping the home button. So basically, instead of the iPad locking after a set time, the clock app moves to the foreground. Like a screen saver on a PC. I'm using an iPad for a control device and would like a different screen to take the place of the control app while not in use. Any ideas??
