The comments about Quicktime X are correct, basic video screen capture is available in Quicktime X, and the article should have mentioned this. I apologize for any confusion.
The only way to get Quicktime X is to upgrade to the new Snow Leopard OS. Like most Mac users, I have not installed Snow Leopard yet. Bad upgrade experiences have taught me to wait for the first service pack / maintenance release to be issued.
In regard to Picture 4, Nukemaster is correct, Artmatic Voyager is the 3D animation program seen in the image. It does have similarities to Bryce, and was developed by one of the Bryce programmers.
There's a different paradigm at play with Voyager. Unlike Bryce, where you develop scenes, Voyager is used to develop entire planets. It's powerful software, enjoyable to use, and renders beautiful 3D landscape animation quite fast on dual and quad core Macs.
