Mood Boards as Writing Tools

A lot of authors use implements to assist them in the creation of their books. While music is not something I utilize for writing, visuals totally are. I make mood boards for my characters, settings, and for the book itself. I even use stock photos that closely resemble my characters in the profiles I outline for them. For a word-slinger, I’m awfully visual. What tools & implements do you use to help you visualize your creations?
