Visualizing is one of the most powerful forms of bringing forth an idea into reality. A teaching called "Living in the End" is an example of this I've come across this year. I discovered it studying the teachings of Neville Goddard. This teaching is more than just visualizing, it's about feeling the goal already being achieved, you do this by adding great detail to the vision.
I've always had a thing for surrealist artwork. A few of the most well known surrealist are Picasso, Dali, and Magritte. You can easily find examples of surrealism in the visual art departments of museums all over the world, as well as in popular culture.
