Virtual Tour uses Quicktime VR (QTVR) technology to take you through
a virtual space. You will need the appropriate plug-in for your system
(Quicktime version 3.0 or later).
QuickTime VR movies, you simply click and drag across the movie image
itself. Zoom in and out with the Shift and Control buttons (respectively)
or with the magnifying glass buttons on the bottom of the viewer. Look
for "hotspots" by seeing cursor changes in the image that will link
you to other areas within the tour when you click on them.
