We didn't make it to the festival this year, but a colleague was kind enough to share a video.
According to Peter: The first few pix are 3-D drawings, done on a flat street, and the images are fantastic. The first 3 are images with a side view of the chalk drawing followed by an image that is viewed from "the right place" to see the 3-D art. Kurt Wenner, world-renowned artist, architect and innovator of 3D pavement art, was the artist for the first one in the this show. There are other smaller 3-D images late in the show.
We enjoyed the video and thought you would too.
