No, not a screensaver but... – Clock Screensaver Review

It provides a simple blue clock in my room at night. It's small, pleasant and launches flawlessly, no ads or superfluous tripe. A simple app, easily launched. Just change the name, advertise its stark simplicity and it's a great little clock with no bells and whistles and still worth .99
