It is worthwhile noting that the first zoomable UI was Sketchpad (ca '62)
-- the writable area was about 1/3 mile on a side and much zooming could be
done in the first clipping window. The next interesting zooming interface
was done by Negroponte in the early seventies (ca '74) -- it was called
Dataland and used one of the very first color bitmap displays -- later
versions were called Spatial Data Management System -- there are some
excellent movies of SDMS.

Cheers,

Alan
