I was looking for a cool clock today for DailyCrush, in the spirit of Daylight Savings Time and all (for Americans, anyway) - and I thought this one was perfect, since it's a nature-y kind of clock, and spring is (hoorah!) right around the corner...
It merely looks like a nicely polished block of wood until you plug it in - and then once you do, the time glows from the inside. :)
