This cleverly designed card folds flat for posting. When the card is opened out and viewed with both eyes a Christmas scene is visible in 3D. Everyone has different eyesight, so to accommodate this the box can be flexed to alter the distance between the lenses and the stereo image, ensuring that everyone may view the scene in focus. The back of the card is an image of the Christmas scene. Published by Courtesy Graphics which is a trademark of The Amazing Card Company www.theamazingcard.nl.

This is a simple kinetic sculpture. When the red ball which hangs from the thread above is moved sideways and released, as it swings from side to side the image of it in the hemispherical mirror behind moves in the opposite direction. If the red ball swings in and out from the frame, the image of it creates other effects. From Design Marketing, 31 St. Johns Road, Croydon, Surrey, England.
