The pursuit of invisibility continues. Following last year's development of a cloaking device that made objects invisible to radar, American engineers have developed a sort of spherical hairbrush that will bend light rays around an object so that you will see the background but not the object itself. So far it only works at one wavelength, but it's a step towards a full-scale cloaking device of the kind that the Klingons will, when Star Trek comes true, acquire from the Romulans. 'In principle,' says one engineer, 'this cloak could be arbitrarily large, as large as a person or an aircraft.' I want one so badly I can taste it. It has one killer app for anybody living in John Reid's Britain. It will conceal your movements from talking CCTV cameras.
