It sounds like an oxymoron but this guy took a cue from The Vos Pad and decked out his own dorm room bed with Light Emitting Diodes. They're even fully adjustable 'allowing me to create every color of the rainbow.' Total cost, according to him in an email: 'Around $25, the LEDs cost me about $0.25 a piece in bulk, and the potentiometers cost about $6 a piece from digikey. I got the LM317 voltage regulators as a free sample from Texas Instruments. Lots of companies will ship you free samples, its a good deal for college students.'"
