The DRM Chair self-destructs after being used eight times.
The chair's designers attempt to make a statement about the Digital Rights Management technologies, which limit the number of times software and hardcore can be used per sale (e-books, games and downloadable programs).
"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," the product's description reads.
The chair, created by Gianfranco Baechtold, Laurent Beirnaert, Pierre Bouvier, Thibault Brevet, RaphaĂ«l Constantin, Lionel Dalmazzini, Edina Desboeufs, Arthur Desmet, and Thomas Grogan, was made during a 48-hour-long hacker competition called The Deconstruction.
