Bryce 5, a 3D design app which specializes in modeling landscapes and animations costs about $70 to buy, but for a limited time (until September 6th), you can get this piece of software for free. All you have to do to get this is to head over to the Bryce 5 site which offers download links for either the Mac or PC version. Although it states that the program will not run under Mac OSX Tiger, David Chartier has tested it and it does work.

Once you have the download sorted out, the first time you start Bryce 5 it will prompt you to log in and register the application for free at their site. You'll probably have to create a new, free account but once you're logged in the registration link Bryce gives you will create your extra-lengthy registration code. That's how simple it is to get your $70 application for free! Just make sure you do it before the deadline of September 6th.
