I found a new inspiration source in a book by Erik Johansson.

Amazing photographs creating a fantasy world almost for real. Surreal and just breathtaking optical illusions. He’s a combination of Roy Andersson, Escher, Dali and many other artists. Check the book out or google Erik Johansson, they say he’s famous on the internet. The book says you can find youtube films with him making his pictures.

You can find Imagine here:
