#2994 — implicit surfaces from older version of Mathematica

This version was developed in version 3 ( I think)
 and was really slow and took up too much memory...
 It works in version 8, but there has to be an easier way...
Pictures are pretty in 8 and it has the real time effect build it
where you don't need all the views.
