For the 100th Gonnagle performance I designed a ‘live video drawing tool’ using webcam, LED spots and processing app.. Software has been written in Processing.. pretty straightforward.. Especially the filters are simple to use but very powerfull.. In the application they are controlled using a midi controller (Korg NanoKey)
