Death Calls the Tune, a project by German designers lab binaer, looks like a regular turntable, until you turn the lights off. Instead of playing "California Dreamin'," this record displays text messages in phosphorus.
By covering the record platter with four bands of light-sensitive phosphorescent paint and replacing the turntable's cartridge with a LED light, the player creates beautiful bands of green that quickly spring to life and then fade away.
A microcontroller determines the pulse of the LED cartridge, allowing for the display of individual letters and, in turn, the fading 50-character messages seen in the video. It's just too bad this psychedelic project's messages are so hung up on death and destruction. [Hackaday via Make]
