3D Surfaces is a PPC-specific plotting program for surfaces of the form
z=f(x,y).  Several surfaces are built into a menu.  User defined surfaces
can be drawn by typing in the function.

One of the nice features it the ability to make quicktime movies out of a 
series of surfaces by using a built-in parameter "i".  The user should
resize the image to something fairly small so that memory requirements do
not become excessive.

The user can position the viewpoint by adjusting values of "theta" and "phi".
Unfortunately, certain values give an incorrect picture.  Additionally, 
the "underside" of the surface is not colored differently from the upper side,
so the correct perspective is occasionally difficult to see.

This program was tested on a PowerMac 7100 running system 7.5.1 with no 
problems.
