Lanterns, with their play of shadows, are among the oldest forms of “displays.” In this Play Test Workshop, we’ll play with light and colors, but we’ll generate the patterns digitally: with two algorithms inspired by nature. They’re called Voronoi and Delaunay and mimic the growth of leaves and the arrangement of cells.

Using the simple, visual programming language vvvv, you can program your own mathematical pattern generated by nature. We’ll use a laser cutter to cut them and turn them into lanterns for the next lantern parade or for your home.

In this Play Test, you’ll learn the basics of the vvvv programming language, gain insight into Rosi Grillmair’s workshop format, and be able to implement it independently in the future or adapt it for your own purposes. No prior programming experience is required.

A certificate of participation can be issued for this training session.

If possible, bring your own laptop running Windows. However, we do have some laptops available on site.
