Watching the seconds go by is a frightening reminder that time pauses for no one, but somehow, a hacker going by the name of Ekaggrat has figured out how to make the process a bit less daunting. The so-called Doodle Clock is an Arduino-powered robotic arm that's been trained to jot down the time with a dry erase marker; once the minute passes, he erases the last digit and rewrites it -- a number beyond what he just erased, of course. Per usual, these things are better seen than read about, so why not hop on past the break and mash play? Smiles await.
