The Movable Filter as a User Interface Tool: "Magic Lens filters are a new user interface tool that combine an arbitrarily-shaped region with an operator that changes the view of objects viewed through that region. These tools can be interactively positioned over on-screen applications much as a magnifying glass is moved over a newspaper." Funky. Sounds a bit like the zoomable interface, but generalised. Hm, and different views of a single object type: sounds a bit like tabs, but different (at work one of the main metaphors in the code is different views on the same data set). Quite different. Mmm.
