This postcard book has pictures that have been made digitally with a computer. Kaleidoscope pictures have been made from photos or pictures that have been digitally altered to make a symmetric round effect. Fractals have been made with a fractal generating program by my daughter. The program made them from input variables by using different algorithms, so it’s all pure mathematics. I wanted the pictures to have consistent names so all the kaleidoscopes are related to handicrafts and fractals have been named by different stones and minerals.
