So you are looking for a clock that stands out? This Laser Time Writer Robot is worth a look. It writes the time using a laser module on a glow-in-the-dark surface. Thanks to a PIR sensor, the writing sequence is triggered every time a person is detected in front of the clock.
The kit comes with an Arduino Uno R3, PIR sensor, push button, acrylic stand, Arduino shield, and everything you need to get started.
