Carwash or Whoville
This lovely artistic picture is from the drainage of a car wash. The amazing look can however see you linking the image to the fictional city, Whoville. Irrespective of which of the 2 you chose, the fact remains that it is a beautiful sight.
This image looks that something that would have required a lot of time, effort and creativity on the part of a graphic artist to develop. It however just lies there, accidentally created. Looks a bit like Mount Fuji don’t you think?
