In this paper, we present Fly, a prototype presentation system that adds a visual structure to presentations. Current presentation software, like PowerPoint, structure slides in a linear sequence. The Fly design introduces a spatial organization that is based on Mind Maps. Using colour associations, spatial relations, and fluid movement, we show how presentation software can structure a meaningful overview of the underlying content.
