Prof. Kemal İnan, Former Dean of Faculty of Engineering and Natural Sciences at Sabancı University and an amateur violinist, wanted to make use of Gráphagos in creating the poster for a concert at Cemal Reşit Rey Concert Hall where he would play along with other amateur and professional musicians. This was the first real job for Gráphagos. I did the selection work, offered him some alternatives, and he chose this one. Below are a photo of the printed poster (reproduced by me in Photoshop with fine-tuning and in printing standards) and the evolutionary history of it.
