chinese artist ai weiwei proposes ‘surveillance camera blocker’ to extend the reach of cans of spraypaint, making it easier to block out security devices.
as well as listing the necessary materials: a spray bottle, a wine bottle opener, a bike bottle cage, a bike brake bar, a screw, and a pole ai weiwei also provides a step-by-step production procedure. of course if building your own surveillance camera blocker sounds too much like hard work, boing boing have found a similar device dubbed the ‘spray close’ on amazon that costs around $11. the device is based on the book ‘do it: the compendium’ by hans ulrich obrist.
