It's the LISP engine that Maple and Mathematica are based on from MIT back in the day. It was semi-recently freed and it's really sweet. It'll take some work (you have to use clisp - the other LISPs are broken, and the GUI is a bit clunkier than most), but it's quite nice. http://maxima.sourceforge.net/ -- Ross Vandegrift ross@xxxxxxxxxxxxxxxx A Pope has a Water Cannon.
