I like that site, but Quicktime VR is pretty dead these days. I can' imagine carrying one of these $$$ tripod heads and messing with the complicated sofware I actually had to do a 3 day training on once back in the 90s.
Now, well, at least from a creator point of view, I am all with technology that allows me to bring a 4oz camera and so all this without a tripod. Here's an example, done without much attention for perfect image overlap, cheesy Canon A590is pocket camera, free Microsoft ICE software (yes, you'll need the Silverlight plugin to watch these, but that's a lot easier to isntall than Quicktime player)
