DROPCLOCK

DROPCLOCK is a wonderful and unique motion clock screen saver that will certainly impress you. Every minute it shows the numbers forming the time dropping into water one by one in slow motion displaying magnificent effects, which make the scene look as it is really happening.

You can either select back or white background, and also small, medium and large screen directly from the screen saver. The price is affordable and the program really worths it. Maybe with the time you could get bored of it, since it cannot be modified or adjusted. It would be great, for instance, if you could adjust the animation speed or if it included other background colors or fonts to vary, or if it also included sound, which would make it even more realistic as the numbers drop.
If you are looking for an original and impressive screen saver to share with family and friends, I would definitely recommend DROPCLOCK. It supports Windows XP/Vista with .NET Framework 1.1 and MAC OSX. It also requires Flash Plugin Version 9.0 or Higher.
