Blinding Surveillance Cameras

A friend of mine was just telling me about a wearable device that Steve Mann made to try to prevent surveillance cameras from photographing him, and coincidently, there's a CNet article on a similar project with the same goal:

Researchers at the Georgia Institute of Technology have come up with an inexpensive way to prevent digital cameras and digital video cameras from capturing that secret shot.

The technology they've devised detects the presence of a digital camera up to 33 feet away and can then shoot a targeted beam of light at the lens, according to Shwetak Patel, a grad student at the university and one of the lead researchers on the project.

I know their approach is more than slightly flawed, but oh how the tables are turning...
