A "Crystal," wireless DualShock 3 is coming to Japan on December 19, PlayStation Japan announced (translation from Polygon). The controller is translucent white and notably not made out of actual crystals.
The Crystal DualShock 3 costs 5,500 yen ($56) and will be compatible with PlayStation Vita TV, which launches on November 14. There's no word if the Crystal controller will ever head westward.
You'll recall this isn't the first time Sony has experimented with natural elements in its hardware.
