Rhino 4.0 Evaluation
This fully functional (except the clipboard) version will save 25 times. After that it is still functional except it will not save and plug-ins will no longer run.

Flamingo Evaluation
Flamingo brings advanced raytrace and radiosity rendering to Rhino. This is a fully functional version except it has limited materials, light fixture, and plant libraries, and it also draws thin black lines across the final rendered image.

Penguin Evaluation
Penguin brings freehand sketching, watercolor painting and cartoon-like rendering to Rhino. Penguin is a conceptual, sketch and cartoon, non-photometric scan line renderer. With Penguin you can create stylized images of your models with an artistic look for enhanced graphic and visual appeal.

Bongo Evaluation
Bongo™ brings professional animation into Rhino 3.0, using familiar keyframe tools found in most high-end animation packages.
