Kaleidoscopes can be done by mirroring, pasting, flipping images in photoshop or with a plug in.
In 32 bit programs, Mehdi Kaleidoscope is a free plug in. It is what I used in all these except as noted in image description. Some images I recorded the settings I used. The first image I ever did was Cloning Gone Wrong...which got Best in Show in my camera club's Creative category.
