Stereoscopic Photoshop demystified. Jason Kottke's posted an amazing primer on rolling your own stereoscopic images with a digital camera and some image-editing software. Possum, my high-school roommate was obsessed with stereoscopes and three-d (part of a lifelong project to write stereoscopic software to help people understand how to visualize n-dimensional space in three dimensions), and would build his own by drawing two nearly identical images and sticking them on the ends of paper-towel rolls, then putting the rolls up to his eyes and unfocusing his vision until the image converged. It all went great until one day, he decided to try to train his eyes to move independently by slowly moving the tubes apart, while keeping the image converged. Luckily, he stopped before he did any permanent damage.
