This edition published in the UK by Phoenix Yard Books Ltd, 2012. The book contains a filter which when moved slowly across the images causes them to apparently move, as a result of the moiré fringes created.
First published in Great Britain in 2012 by Dorling Kindersley Limited, London. This is a particularly good book of optical illusions. One optical illusion in the book illustrates the reverspective principle, which is illustrated with a pop-up.

This is an amazing illusion in which, as you walk around a room looking at the dragon, it turns its head so that it appears to be following you. The design was downloaded from the web and constructed by John Davenport circa 2008. The design was originally produced for Gathering for Gardner 3 in Atlanta, Georgia, USA 16-18 January 1998. Copyright 1998 Binary Arts Corporation. It was inspired by the work of Jerry Andrus.
This was created by Ian Ginn in 1984. As you view the hologram from different angles four billiard balls appear between the fingers of the hand. Look at both photographs to see the effect.
