Use TouchOsc for Android or iPad to control generative visuals in Processing! This project focuses on using Toxiclibs libraries in Processing to map geo-tagged locations on a map of the world, with rotation on the x and y axis controlled from an Android mobile device.
This project can be turned into a musical instrument using midi-enabled software such as Ableton Live or Reaktor.
