Zoom Quilt (Note: link fixed on January 3) is a collaborative art project based on Macromedia Flash that illustrates what a 3D Zooming User Interface (ZUI) might look and feel like. ZUIs work by creating an intuitive information landscape. The user moves "further away" to get an overview, or "closer" for more detail, while keeping a sense of orientation and structure that traditional pop-up windows and dialogs can't match (see research papers and Java demo). Zoom Quilt was assembled from different frames of content contributed by various participants. For another Flash-based example of a 3D zooming experience, see also the older Christmas Zoom.
