This lithophane was created by Steve Nicholls from a digital photograph of John Davenport. To view the image properly it must be held up to a light. Steve is a UK puzzle expert and 3D printing enthusiast. The lithophane was created using an affordable 3D printer. The photographic image was converted to a grey scale and then turned into a 3 dimensional height map that is 3mm tall. The map has been printed in 30 layers on a THREEDY 3D printer using translucent plastic.

The Hyperscope is a viewing device that uses a system of mirrors to increase the apparent distance between your eyes, so that they see as if they were further apart. This allows you to see the world in a different way, more exciting and with more depth. This one was purchased in kit form from Grand Illusions Ltd in 2015. www.grand-illusions.com. Design and concept by Terry Pope www.phantascope.co.uk.

This is a well made wooden example of a well known optical illusion. The wooden construction allows for the two wooden table tops to be interchanged. The table tops are in fact of an identical shape and size. This looks impossible, but swapping them over proves that the table tops are indeed identical, although your brain finds it impossible to believe this. Purchased from Grand Illusions Ltd in 2010. www.grand-illusions.com.

The novelty is that this single sheet of paper has been slit in such a way as to allow it to be folded into the booklet of 8 pages.

The exhibition was mounted as part of the South London Women Artists Collaborative residency at Conway Hall, Red Lion Square.

This card has two layers, joined in the centre by a rivet which allows the top card to be rotated on top of the bottom one. The top card is clear plastic with black lines printed on it and the bottom one is white with a heart and coloured lines on it. When the top card is rotated the changing moiré patterns create the effect that the heart is rotating. Miracle Cards, copyright BIZARR/m. schmölz. www.bizarrverlag.com.
