Here's a QuickTime interactive "Virtual Reality" movie of the Boston skyline.
Taken from the roof of Baker House.
This is a 3.7MB file (not small), and requires QuickTime to run on your machine.
QuickTime is native on Macs, and is a free download for Windows machines.
Here's the link to the "Virtual Reality" movie:
Arrow keys (or the mouse) let you to scan and pan (up/down, left/right).
