In a statement against the Digital Rights Management technologies, which limit the number of times software and hardcore (e-books, games and downloadable programs) can be used per sale, a group of designers have created a chair which self-destructs after being used eight times. "A small sensor detects when someone sits and decrements a counter. Every time someone sits up, the chair knocks a number of time to signal how many uses are left. When reaching zero, the self-destruct system is turned on and the structural joints of the chair are melted," reads the product's description. Entitled the DRM Chair, the design was conceived during a 48-hour-long hacker competition called The Deconstruction.
