If anyone would be interested in this Computer Algebra System:

I hear it's nice. Looks like it's free.

Maxima CAS looks /very/ nice for being free software. I personally payed for the Mathematica student license and love it...but Maxima looks great....this is the first time I have heard about this....being open source I bet it has a number of avalible plugins. It would be neat to set this up on a Linux box and create a little website that uses the open source Maxima as an engine for computation of Algebraic equations from a website's input form (php).
