Guardian Camera Club: Gethin Thomas on conceptual photography

1 Making that cat's cradle was the closest I ever saw my father come to playing what anybody else would call a game. I actually froze a cat's cradle into a block of ice to do this. Photograph: Gethin Thomas/Flickr

2 These are not Bokonon's words. They are mine. My soles, my soles! My soul, my soul. The soles of the feet are significant in the religion of Bokononism Photograph: Gethin Thomas/Flickr

3 The seed taught the atoms the novel way in which to stack and lock, to crystallize, to freeze. This is the geodesic dome of the Eden Project which I visited last week. I thought it apt that the roof of Eden reminded me of crystals of ice, that brought about the end of the world Photograph: Gethin Thomas/Flickr

4 It was a grand AH-WHOOM. I opened my eyes, and all the sea was ice-nine. Fossils frozen in ice rather than rock. Ice nine destroyed all life on the planet. These fossils were some patterned flooring I found Photograph: Gethin Thomas/Flickr

5 Nothing in this book is true. The inventor of ice nine was playing with a cat's cradle when the bomb he helped to design exploded over Hiroshima. Ice nine would later cause the world to freeze. http://www.flickr.com/photos/speedtree/7287526394/ Photograph: Gethin Thomas/Flickr

6 Cat's Cradle by Kurt Vonnegut. This is the image as I saw it for the final scenes in the book where the Earth turns to ice. A crystal of "ice nine" escapes into the environment and freezes all the water on the planet. I have a cat's cradle just visible, frozen into the ice Photograph: Gethin Thomas/Flickr
