Cubes first attracted attention as the stars of a popular TED talk. Now these ingenious electronic toys are available for sale. They’re tiny blocks with color LCD touch-screen tops and the ability to run apps–and they know when you flip them over or touch them together. All that clever technology makes word games, memory challenges, sliding puzzles and other classic pastimes into all-new, highly interactive experiences. One caveat: Cubes only work when they’re within a short distance of a Windows PC or a Mac.
