These four images were created with the same photo using smart object in Photoshop cs6. By copying the smart object in the shape of a triangle and flipping it around the page, the smart objects are all connected to the same clipping mask. That means, when you move the photo that is clipped, it will update all of the smart objects, not just that one. The results are a self updating Kaleidoscope that give you results like the following photos. Pretty cool!
