John Dyer has created a 3D panorama trick in JavaScript, which works in Firefox at the moment. It creates a series of div columns, and then puts copies of the image in each column. As you move your mouse across the image, it stretches the columns vertically along a sin curve to fake the 3D look. And then it destroys your processor.

John — I'm putting together a tutorial for making 3D panoramas using Papervision3D (example) and I though I would release some pretty pointless JavaScript code I wrote a while back that attempts to make a panorama using just JavaScript.
