Beach Chair was a short computer animation test clip created by animator Eben Ostby for Pixar in 1986. It depicts a chair walking across the sand, dipping its leg into the water, and then moving along. Ostby made the project, with the feedback of John Lasseter, to work out details of rendering software. It was exhibited at SIGGRAPH in Dallas in 1986, along with Lasseter's landmark computer-animated short Luxo Jr. and another test project, Flag and Waves by Bill Reeves.
