Today I co-ran a session called Ars Combinatoria at Transmediale. From the blurb:

As a young man the philosopher and mathematician Gottfried Leibniz was interested in creating an ‘art of combinations’, which would allow people to create interesting new inventions from a set of basic elements.

The ‘Ars Combinatoria’ project is about creating new works with public domain or openly licensed images, sounds and texts.
