Justin Quinnell is brilliant. His website is completely focused on pinhole photography and taking it to the next level. The above shows his "Stereo glasses" and the images are what the left and right eye see respectively. He is so inventive in his cameras and trying to make them into the next big thing. He works a lot with the long exposure aspect of pinhole as well as the simplicity of the camera obscura with his take on his "I-scura"!
