PLAY is an origami MP3 player designed by Jun Pyo Kim, Keun Sol Kim, Sung Mi Kang and Joo Hee Park. The white square is unique because to control its functions one much fold the player.

Folding the origami MP3 player into a triangle in one direction will allow you to 'press' play while folding it in the other direction will initiate the pause function. Leaving it as a square will stop all functions, and sliding the player into two conjoined triangular shapes will speed up the sound.
