Pools are not exactly the most projection ready surface, and initial brainstorms produced many more challenges than this team had anticipated. In researching a solution, they had to overcome the fact that projection doesn’t work on the surface of water, it becomes distorted if you project through it, and pool parties are notorious for more standing than swimming. Most people reacted as any any normal person would, and promptly put in and order for 65,000 ping pong balls, enough to cover the entire surface of the pool. To go with their new screen, they created an application which mapped to the pool and displayed a floating river of graphics, pulled by an invisible tide. Audio reactive visuals bumped along with the various dj’s and musical acts taking place poolside. The tactile quality of swimming through ping pong balls, combined with animated colors and light created an interactive event worth telling stories about.
