J. Nathan Matias is talking now, and he’s brought a physical hypertext sculpture! Being a savvy blogger, he’s blogged his talk already. The sculpture, The Philadelphia Fullerine, is a geodesic sphere, which is kind of like a huge AD&D dice with sixty or so sides. Each triangular side has a photo or a short quote and an audio narrative sequence to go with it. You read one side at a time, and continue to one of the three adjacent triangles to continue reading. It’s a spatial hypertext, that is, the nodes are connected by proximity rather than by links. Matias also talks about how he’s used hypertext tools in developing the sculpture.
