Numerical clocks can be found in all shapes and sizes—some with cat eyes and tails moving back and forth, some that require a team of workers to maintain (Big Ben) and those that sit on our nightstands. In an effort to do something different, Instructables user drj113 designed a Word Clock that spells out the time with the help of an Arduino Duemilanove—or not. His clock is actually designed to use either the Arduino board or an ATMega168 with the same image.
