I am really happy that you like it. To make this picture I have used Maple. Tomorrow I will send to this mailing list the source code that I used (now I do not have access to it). So anybody who has Maple can play with parameters (such as radius of spheres and cylinders, distance between the spheres, length of coordinate axes, colors and so on). By the way, Maple generates really 3D object (not just a picture) in the sense that one can interactively rotate it (using the mouse).
It's a pretty sweet logo. It would make a really nice icon for a GUI
interface to jbofi'e or something. Just out of curiosity, what
program did you use to create this?
