Registration for Gravitation3D and the Gravitation3D Screen Saver

If you find G3D worthwhile, please take a moment to consider making a PayPal donation to help keep this site in existence.  To do so, you can click on the PayPal link below to donate securely with any major credit card.  Donate any amount and I'll email back a code to remove the "Demo" text from the screen.

         

Contributions can also be made by check to my snail mail address below.

One of the best and easiest ways to help this site is simply to link to it.  Help spread the word!

If you plan to use this program for any commercial purpose, such as using it in a presentation or as a demo to sell your product, please contact me for licensing information.

All the best,

Roice
