These clocks quickly grew in popularity due to their simple but elegant design, displaying the time in large white numerals against a black background.
The fun and beauty of this screensaver is that it can effectively turn any Windows or Mac OS X computer into such an elegant and useful clock. The bigger the screen, the bigger the clock.
Some options available to this screensaver, that the original flip clocks did not possess, include the ability to switch between a 12 and a 24-hour format.
