I stumbled across this website today and thought a number of you would find it interesting. http://www.cs.berkeley.edu/~sequin/SCULPTS/scherk.html
The website provides a link http://www.cs.berkeley.edu/~sequin/GEN/ to a free Windows based program that generates some really neat geometric forms. It is simple to operate and you can save the objects in .stl format. I don’t know how many programs support that format or if there are any available format translators for it but I found that by importing into Rhino (which does) and then exporting to .obj I have some really neat objects that can be imported into ZBrush.
I love programs that produce parametric geometrical forms and I think you’ll enjoy this as well.
Have fun!
Brian.
PS - The generator site also has a link to a program that generates EscherSpheres which sounds interesting but I haven’t been able to get that one to work. It seems to be missing a file needed to operate properly.
