date started: 090911 name: windtracing 2 - paris version ( 20100215 ) [ prerequisites for running: the Processing programming environment - get it here: http://processing.org/download ] This sketch traces wind movement. The thinner line usually starting at the top left shows longer-term wind movements, moving in the compass direction that the wind blows in. The larger line starting at the screen centre is a zoomed in view of the current wind blowing - with the historical data tracing back, as it were. keys/usage: relax and watch :) otherwise: shift - pauses/resumes playback arrow left/right - set playback to go backwards or forwards [ / ] - to skip backwards/forwards one week in time.
