The left thumbnail is a full QTVR movie, a very large download.
If you have a slower connection, download the individual QTVRs instead -
eg. molecule.mov, neuronfire.mov, & panorama.mov

Each QTVR will have a set of controls in the bottom left corner.
You can zoom in, zoom out, view "Hot Spots," or go back.
