Above graphic created with FFermat (Mac only).
Fermat is a computer algebra system for Macs (68K or PPC) and Windows by me, Robert H. Lewis of Fordham University, that does symbolic calculations, graphics, and numerical calculations. It is extremely fast and extremely economical of space. The main version that I care most about is oriented toward polynomial and matrix algebra over the rationals Q and finite fields. On the Mac side, there is also a "float" version for graphics.
