Bumpy Sphere

This was a mathematical shape generated with a java application located here, using the following formula:
? = 1+.2sin(8?)sin(4?) where 0 ? ? ? 2? and 0 ? ?? ? ?

To generate a spherical object in the application, click the View Settings menu item, select Set Function Type, choose the desired function, and set to Spherical.

The application will then let you save the generated object as an stl file, under the File menu item.
