Insane51 started his street art career in 2006 in Athens. Inspired by huge murals in the city he finalized his first own mural in 2007. At this point he was focused on portraits and experimental techniques with forms and colors. Afterwards he started specializing himself in photo realism and overlay-murals, something that is his very own handwriting know. The insane aspect of his artworks is the ability to place two murals on the same surface. What you cannot see with the human eye, only appears if you look through 3D glasses. This technique is only possible because of the domination of photo-realism and his specific control of colors.
Your building would look a lot better with the art of Insane51 on there!
