I saw a hudini video tutorial a few weeks ago that shows how to use a noise field to create particle trails that look like electronic schematics. I really liked the effect and recreated it using a small processing script. To create the effect I set up some particles, that use a noisefield to influence their velocity. Before the velocity is added to the particles potion the vector is normalized and then each component is converted to an integer value - this limits the values to the x and y component to -1,0 and 1. The resulting vector is then scaled to the original length of the vector and added to the position of the particles.
