I love clock screensavers because they serve the dual function of keeping my screen from burning in and also showing me the time. The latest clock screensaver I’ve come across is this grid-based one from Build. The screensaver shows the time in hours, minutes, seconds, 10ths of a second and 100ths of a second by filling up black squares in a grid. Check out a preview of the screensaver here and if you like it, you can download it for Mac or PC. [via]
