The flip-style clock screensaver by Yuji Adachi (9031.com) has been around for a while now, however I reckon it’s just so cool and if you haven’t already tried it out then encourage to download it. I like it not only because retro styled flick-clocks are back in fashion, but also because it’s both beautiful and practical.  Best of all it’s free!
