Imagine tiny computers that you can arrange like dominoes or Scrabble tiles in order to play a game, tag photographs, or create a sequence of music. Each Siftable has a tiny screen, accelerometer, proximity sensor, and Bluetooth radio so you can put two Siftables side by side, or "tip" information from one to another. Tilt a Siftable forward to play music or back to rewind. Sort Siftables showing photos into piles to organize them as they make arranging information like arranging physical objects. There's no price or launch date yet, but MIT and Taco Labs are talking with factories about producing Siftables cheaply.
