Crystal Cave

by Roger Penrose, Haifa Khawaja, John Martineau

'The patterns later became the bestselling Altair Designs – coloring books where each design could be perceived in an almost infinite number of ways. Ensor and I worked together for many years. I developed new hi-tech geometries inspired by the Sarghatmish design based on circles and then spheres that change size and position to generate "perceptual" 3D spaces and architectural structures. Altair represents a type of design that literally changes before your eyes. They are designs that conjure images and patterns in the mind's-eye of a user making whatever is "seen" unique. Altair designs, then, are not like other coloring books – there are no fixed images to color and they serve to stimulate the visual imagination.' (Roger Burrows)

About the author

Sir Roger Penrose (8 August 1931 - ) is a British mathematician, mathematical physicist, philosopher of science and Nobel Laureate in Physics.

He is Emeritus Rouse Ball Professor of Mathematics in the University of Oxford, an emeritus fellow of Wadham College, Oxford, and an honorary fellow of St John's College, Cambridge, and University College London.
Penrose has contributed to the mathematical physics of general relativity and cosmology. He has received several prizes and awards, including the 1988 Wolf Prize in Physics, which he shared with Stephen Hawking for the Penrose–Hawking singularity theorems, and the 2020 Nobel Prize in Physics "for the discovery that black hole formation is a robust prediction of the general theory of relativity".
