Steve Mann's Chair from a #cyberpunk dystopia, exhibited at San Francisco Art Institute, 2001.
It revolutionizes seating by being the first product to offer a cloud-based, Seat as a Service solution. The chair comes with a dozen of spikes. It's connected to a global license server. You would obtain a Seating License to retract spikes. When license expires, spikes will be activated again. Also if you don't accept our ToS, remain standing!
