Here are the source documents for two different ball based projects that I from following tutorials.
This one is a background image that I have done and I featured it on my 3Dmitchell.com 3D & 2D images page. It is a large file because the resolution is decently high.http://3dmitchell.com/freeDL/ball.psd Size: 27.1 MB **LARGE DOWNLOAD**
This is just a 3D looking ball that can be used for a button or anything you wish to use it as. You can change the color, the size, add multiple copies of it, anything you want.http://3dmitchell.com/freeDL/ball2.psd Size: 283 KB
