The Anaglyphs are used effectively to help students to visualize functions of multi-variables in Calculus and Linear Algebra.
What are the other effective tools for visualization in Applied Mathematics?

I have used VRML in the past, see these examples:

It has been largely superseded by X3D, see in Wikipedia. Similar dynamic 3d graphs can be made with gnuplot or some R packages.
" I wonder if this tool helps for functions of more than 2 independent variables. If so, how? "
The 4th variable is represented as a colour.

or by projection onto 3D spaces:

three dimensional graphs may be another type of representations.
