Generative design

Holger Lippmann is one of a group of digital artists who use computer algorithms to create their designs which are then printed for exhibition. I'll let him explain:

the e-pastel TAR_GRID series consists of a X Y axis grid of bezier vector curves. a seperate vector curve class defines all vector properties such as color, transparency and/or stroke weight. to later position them within different grid arrays. different keyboard input values are used for a layered image build up; coloring, sizing, transparency, count and density of star pedals
