FacetZoom

Raimund Dachselt presented FaceZoom, a widget for quick navigation, e.g. for a tree structure [1]. I liked his characterizing “a stacked treemap” – which explains nicely what the widget does and where the efficency can be found. At TEI’08 he gave already a nice private demo on how this can be linked to mobile devices and how to use a off-the-shelf phone with an accelerometer as controller.
