Many design and technology companies produce DIY kits for devices, smart objects, and robots that the user assembles as though with advanced sets of Lego bricks. Inspired by classic games such as chess, checkers, and mah-jongg, Sifteo Cubes are a hands-on interactive game system. Each cube contains a tiny computer chip and connects to other cubes, sensing their motion and position, through a wireless network to an application on a nearby computer. The cubes can be used in various games, including a spelling game in which they are rearranged until a word is correctly spelled, at which point they light up and highlight the word. David Merrill and Jeevan Kalanithi designed the cubes while graduate students at the MIT Media Lab, and they have since formed a company, with designer Brent Fitzgerald, to produce Sifteo Cubes, games, and software.
