Unfortunately, there is nothing for a stock iPad.
There is a tweak for jail broken devices called "BossPaper" in Cydia (the jail breaker's "App Store"). However, it was developed during the time of iOS 4.x and everything I've read has people stating they have issues running it on iOS 5. A few people have stated it worked on an iPad2 running 5.0.1 but it had a few glitches.
It was not updated for iOS 5.0.1 and it doesn't appear any work has been done on it since iOS 4.x. So, I highly doubt that it would work on iOS 5.1.1.
Long story a bit longer: As far as I know, there is nothing like what you want that is available and current. Sorry.
