I would like to use your image for my cover. It is an eBook for teenagers who are going to experience a thought experiment in search of the perfect ball that should represent the Big Bang. Later I want to use your image as a glass spaceship. I would like to receive your approval for the use of this image "drapa_genisys8k.jpg", Sincerely Rene Philipsen in the Netherlands rene.philipsen@icloud.com
