This is 3D OpenGL eye-candy for Mac OS X, complete with customizable settings, and full source code.
The implementation might be interesting – the options interface is build using Interface Builder, Objective-C and Cocoa, yet the actual drawing code all happens in C++ using OpenGL.
Props to the folks at Cocoa Dev Central for posting a pair of tutorials that got me started with building screensavers in Xcode.

I have to say that this is probably the best screensaver I’ve ever seen. I used to have it, but then I had to wipe everything off of my Mac. Now I tried to download it again, and it won’t work. Any tips on how to get it to work?
