Really cool paper stuff! A working pipe organ, a working clock, a pinhole camera, Cinderella's Castle, Disney's Tower of Terror, a movable steam engine, Howl's Moving Castle, a working version of The Game of Life, and much much more, all found via the wonderful Paper Forest weblog, which has links to lots of paper projects, automata, ephemera, and art. One or two of the paper templates are for sale, but most are free and online for your downloading pleasure. I just love this weblog.
