(basic examples of the book as a medium) exhibition-event on the nature and characteristics of bookworks, Artpool P60, 2002.)
“An opened book can be symmetric formally but because of the different information on its pages, this symmetry becomes damaged. Therefore, a book originally is an example of symmetry-violation. We are able to use this approach since the book has become a possible medium of concrete art. These "bookworks," by reversing time, show the phases of the history of books. Furthermore, they attain the status of a counter-example which does not violate symmetry.” (György Galántai)
