Sentient City Survival Kit: gadgets to foul the surveillance state and amuse the bearer

Mark Shepard's "Sentient City Survival Kit" video shows a series of experimental designs for devices intended to jam surveillance, control and boredom in everyday life; there's a commuter's coffee cup that networks with other commuters' cups to form covert, train-long mesh-networks; a CCTV-foiled umbrella studded with infrared LEDs, and more interesting, if somewhat vapourware, gizmos.
