Well, the program is called Apophysis, but to make that particular verison I used the Apo 3D hack. I wouldn't suggest starting with 3D hack, as making things in 3D is naturally more complicated than making a 2D fractal.
You can get the latest Apophysis
here, with a good selection of tutorials
here
If you do grow interested in using the 3D version, it is available
here

Yeah, I probably should go back and tweak some things in the gamma and brightness for that one...but Apo 3D takes ages to render, and uses a lot of resources, so I've been putting it off
