Pulsar is a psychedelic strobing night light that doubles as a useful flashlight. Adjust the pulse rate of the color flow and randomness of the colors. Bathe your friends in the warm glow of color or read a book in bed without bothering your partner. Choose from four basic shapes: ellipse, lightning, star or diamond. Or simply rotate the phone to change colors. Set the pulse to slow motion for ambient party light. And the best part, it's free!
