Have you ever seen behind-the-scenes footage of a movie where the camera is mounted on what looks like miniature railroad tracks? You can see the camera sliding across the terrain on these tracks to provide a smooth camera shot–essentially a moving tripod of sorts. Well, that kind of cool cinematography is now available for your iPhone and Android videos or any DSLR camera. It’s called the Pico Flex Dolly and I think the video below pretty much speaks for itself. Amateur videographers only dreamed of this kind of equipment and here it is available for just $100 (includes the arm, shark clip and case). You can go ahead and add this to my Christmas wish-list!
