Yet another particle movement simulation, this time a biased random walk. Balloons randomly move around, but have a tendency to follow the mouse pointer (unless it stops moving for a while, then they get bored). If you leave food on the canvas, they will usually hurry to get there first (sometimes they're not hungry, though). They eat strictly in the same order you dropped the food, as real fish rarely do, but maybe hungry balloons in a fishtank? Who knows.

The balloon color is determined by their relative position to the mouse pointer. Basically: Vector angle between pointer and position determines the hue, distance determines the value. Since the angle relates to the origin in the top left corner, this creates a nice color hue effect that changes from left to right. Saturation is fixed, we could use speed for example, but.

Strange thing, once you draw a lot, they really slow down, because there's not much accelerating to do to reach the next bread crumb in the trail. So they just lazily wander from crumb to crumb. Gets a little frustrating. Again, I apologize[*].

You could call it zen drawing, if you want to call it anything.
