A German art project could help the British avoid the oppressive proliferation of surveillance cameras in their country. The I-R.A.S.C is simple, consisting of a circle of infra-red LEDs mounted on a headband. The infra red is invisible to The Man, but will cause CCTV cameras to flare out over the face of the wearer, obscuring his identity and making this the digital equivalent of a hooded sweatshirt.

This is not a production unit, but given that you'd only need a hat, a battery and a few LEDs, you could easily knock one up in the garage.
