Ken Murphy, a computer programmer in California, built a rig to photograph the sky once every 10 seconds for a year. The resulting time-lapse video collage is a kaleidoscope of shifting weather patterns. Murphy's project is one of more than 150 featured in The Art of Tinkering (released this month). Karen Wilkinson, one of the book's editors, says it shows time-lapse photography is now more accessible than ever before. "People are even writing apps for it," she says. True to form, the book includes a guide for mastering the art of time-lapse.
