Computational Design of Linkage-Based Characters EXPLAINED: A system for designing linkage based characters using a catalog of linkage types. CHOSEN: I chose this project because it shows a new approach to designing complex linkages. This gives users without large amounts of… Continue Reading →
Here’s the example I shared in class for using OSC with the Photons. It’s also available as a Gist on Github.
