Ramon Bruin is one of our favorite artist who are good at playing with optical illusion and create amazing 3D drawings. And this time, he has been adding even more complexity to his illustration repertoire. Using multiple sheets of paper he creates images that look like stacked towers when viewed from just the right angle. His drawings are done mostly in graphite pencil with an occasional colored pencil, ink, or acrylic to add a splash of color. Take a look at Bruin’s latest collection or check more work on his site.
