SwampFest final day

There was a guy in who has an ongoing practice of making large inflatables. He made one at Swampfest for the kids to run around inside, or just sit and be in a private place. He was telling me about having long tubes that ran through a school one year that he and an art class installed as a surprise during class time. When the class change came, everyone discovered, a three foot cylinder snaking through the hallways and stairways. The next discovery was that it was a like a giant drum as everyone began tapping on it.
