Visualization references:

Animabob: An interactive volume rendering tool. Open-source, and available for any flavor Unix with OpenGL or Mesa3D support.

Viz5D: Another volume rendering tool. Also free!

Viz: Yet another volume rendering tool. Also free! All the volume rendering tools shown here have unique strengths the others lack, so they're all worth checking out. Worth noting: Animabob and Viz use the same file format.

Animating the Evolution of a Field: Platform-independent methods for rendering in 2D. Includes free source code. This site is very helpful if you don't have the resources or patience to cope with one of the resource-hoggy but lovely volume rendering tools.

WinBob: Another option for looking at 2D slices of a volume. Uses the same file format as Animabob and Viz, and runs under Windows. WinBob lets you load a volume file and look at any 2D slices parallel to the x, y, or z axes.
