Not interested in being captured on CCTV? Wear an IR light emitting headband. Apparently this device from Germany offers "protection from the protection". This is courtesy of Boing Boing, where one commentator says this is only useful to thwart IR cameras as most CCTV cameras have an IR filter attached. I don't know if this is the case, but it's clever. See Google's translated version of http://www.oberwelt.de/projects/2008/Filo%20art.htm
