Magic eye viewing instructions : all you need to 'see' the 3D illusion on the front cover are your two eyes and some patience ! One easy way to do this is to hold the book right up to your nose. The Magic eye image should be blurry. Focus as though you are looking though the image into the distance. Very slowly move the book away from your face until you begin to see depth. Now hold the book still, try to blink, and the 3D hidden image will magically appear.

In a smaller format, this collection of 3D images is all connected to the festive season.
