I direct your attention to this cesium atomic clock on a chip, which intrigues me. I want one. (My email would always be sent out with a proper timestamp if I had one.)

Why not an indie game for today's link? I give to you Polynomial. It's a straightforward little 3D shooter but you fly through abstract generated fractal models -- it's gorgeous. Available for Mac, PC, and Linux, too! (Just be a little cautious about setting fullscreen mode on OSX.)
