This image is not cgi or a miniature; it is a real mountain slope where artist Sonja Hinrichsen created this beautiful pattern simply by walking in circles. The robotic perspective of this concept is the way the photos and the video were shot, not by a helicopter but by a small (but quite expensive) octocopter by video production company steamboat aerials. The Cinestar8 costs around 10k $ but it can carry the ~400gr camera while being stable enough to produce this result. The video is similar to that of a hugely expensive helicopter shot or even better considering the lack of downwash a helicopter creates. This video is already very popular but almost no-one cares how it was shot, most people focus on the art-concept (reasonably so), maybe drone filming is starting to become quite mainstream. You can enjoy the full scale of it at this video on vimeo and you can find high-resolution aerial images here.
