If you use OS X, then you've got an application that'll waste hours of your time just sitting on your hard drive.
Say hello to Applications > Utilities > Grapher.
We needed a simple Fourier square wave for a book. Just type in the equations, and out it pops.

But the time wasting comes from playing with its example graphs.



Did I mention that they animate, and it can export Quicktime?




Yes, Grapher is great fun. I used to bust it out during my differential equations class to get a better idea of what the professor was talking about. Later I used it to generate plots for a paper I was doing in LaTeX.

You have to wonder if there is any of the old code from the graphing calculator story. http://www.pacifict.com/Story/

Is this available for other unix-based OS'?

Knitpick: mine sits in Applications > Utilities > Grapher. Great find though, I think I'll waste a good chunck of time with this ;)

Grapher used to be called "Curvus Pro X" before Apple bought it. Unfortunately Apple have done nothing with it in the three years since. The help is missing certain subjects and some parts don't work. So brilliant yes, but severely neglected.
