Processing

Processing is a programming language intended to simplify the creation of programs with graphics, data visualization, and user interaction. I got interested in it after seeing some cool examples online of what it could do. Presentation This is (more or less) the presentation I gave at Bar Camp Grand Rapids, 2009. Examples

Many Circles - Draws circles under the mouse cursor.
Simple Draw - Draw with left click, erase with right click.
Rotating Box - 3D box rotates with mouse cursor
Random Letters - Displays random (usually) nonsense words.
Terrain 2D - Displays randomly generated terrain in 2D.
Terrain 3D - Displays randomly generated terrain in 3D.
