CP Electronics can save businesses large sums of money every year by automatically controlling lighting levels. But the equipment on ‘stand by’ still uses parasitic power. Could we devise a method to show electrical data for 70 products in a feasible way? We have significant experience in ‘information management’ and came up with an information wheel (technically called a volvelle) which could also act as a marketing give-away. We have designed these before, most notably for Richard Attenborough’s 80th Birthday celebrations. The client finally decided that their figures weren’t low enough to provide a definite marketing advantage and, sadly, the design didn’t go ahead.
