GOLOZA Projection Alarm Clock, Digital Clock with 180° Rotatable Projector, 3-Level Brightness Dimmer, Clear LED Display, Progressive Volume, 9mins Snooze, Digital Alarm Clock for Bedroom

While there are far cheaper ways to tell the time in your room, this is one cool clock. I love its two main features – crisp red digital numbers visible all day long and the red projected display on the ceiling visible clearly at night even if you're not wearing glasses. Light intensities of both displays are variable. The clock is quite lightweight. The only drawback is that it needs to be plugged into the mains. I wish it had a provision for rechargeable batteries.
