Ah, Illustrator. If more people knew you could make this sort of stuff this easily, and your interface weren’t rooted in 2001, people would love you as much as Photoshop. This is great stuff, Veerle; how’s about some more tips and tricks for making mathemetically-correct curves and stuff? I wrote up my experiments in trying to create such things in Photoshop but I’m sure it’s probably a lot easier in Illustrator.
