This clock, engineered by Angela Yuan, is awesome. Every minute, this clock erases itself, and then re-etches the correct time. Man, I used to have so much fun playing with the Etch-A-Sketch, when I was a kid. I would spend about 5 minutes drawing a gun or something, get bored, and throw things at cars over my backyard fence instead. One time, it was a ziplock bag of pee. Good times… good times.
