Triangulation is an online interface which I coded for Patternise http://www.patternise.com/, in collaboration with Obsessive Design http://www.obsessive-design.com/.
It is a proof-of-concept for user generated products, in this case a pattern which can be applied to objects. The system is based on intersection points of lines in golden rectangular modules constructed by the graphic designer, which can be dragged into the workspace by the user. Some of these can then be activated or deactivated, and connected together using an algorithm.
