Wolfram, the company behind Mathematica released their new "computational engine" a while ago, with the aim of the project to "make all systematic knowledge computable".

Whether they succeed or not, I don't know (I doubt it), but it can do some very neat things nevertheless, especially in the area of maths and science and is a brilliant piece of software. It can do everything Graphmatica does and more.

Here are some examples...

http://www65.wolframalpha.com/input/?i=partial+fractions+(x^2-4)%2F(x^4-x)

EDIT: Uhh the formatting has gone to hell here for some reason. Fix'd
