If you're the kind of cheeky prankster who loves winding up your friends then Smashed Screen could be the perfect download for your Palm.
The app basically loads an image of a damaged screen onto your Palm display, giving the impression that your device has actually been ruined. Click on the Home icon though, and the smashed screen will disappear, and your system will be 'magically' restored.
Granted, Smashed Screen is a bit of a cheap joke and it's not the sort of thing you'd keep installed on your device for too long. However, the illusion is very effective and might help you raise a chuckle or two.
Frankly though, if you're installing applications like Smashed Screen you must have far too much time on your hands.
