I was asked to create a video of "play" that Dr. Stuart Brown could use in his presentations on the social, developmental, and cognitive, neuroscience aspects of play ("unstructured fun"). He asked specifically to use footage from a physical play workshop I videotaped with Exuberant Animal (exuberantanimal.com), where Dr. Brown also participated and lectured. Much of the footage can be seen in Exuberant Animal's video, but changed to de-emphasize that company, but focus on what adult play can look like.
A little weird that the video looks fuzzy on Vimeo.
