There was some discussion last month in this newsgroup about variable mirrors. To prove that there's nothing new under the sun, see pg. 20 of the December 16th issue of Design News. Profs. Waddell and King of teh University of Strathclyde have developed such an animal, although the novelty is in the mounting and control of the curvature of the plastic film, not in the basic principal.
