Copycoder: clever use of an array of cylindrical lenses to scramble and unscramble large font messages- a modern "secret code" toy. The refractive optics invert slivers of an image to encode or decode it. You can scramble an image by photocopying a message covered with the array plate, or go to copycoder.com and a program will scramble a message that you can print out to send to anyone that also has the lens array. Invented by Steve Ostler from the UK.
