For this processing noise-field exploration I created some particles that wander around on a plane. The location a particle goes to is calculated from its current location using a noisefield. I draw a small line from the current to the previous location and make the lines fade away very slowly so the trails the particle create while wandering around can be seen.
You can reset the particle locations to a random position by clicking on the sketch.
