Hodgin:
One hundred circles of nearly equal radii are positioned equally spaced into a circular pattern. Each circle is responding to two specific forces: gravity and elasticity. Their positions are represented by a single pixel whose alpha is inversely related to the circle's distance from the center of the space. All of the circles are slowly pulled into a weak gravitation field, which exists near the center of the space. This is what starts them into motion. If two circles happen to collide, there is a flash of white to mark the position of the collision (unless the collision occurs inside of the original circular starting pattern, which would create a black collision marker). The collision forces the circles away from each other. To help facilitate collisions, each circle checks to see if it is near any of the other circles. If the distance separating them is small enough, they become drawn towards each other.
Tarbell:
This is beautiful. It's hard to imagine how only the intersections of circles could build such an organic-looking structure. I am reminded of a biological cell under viral attack.
Ngan:
I like the explosive and powerful beginnings. The composition has a kind of “unity in variety,” which makes it quite compelling—I think it could be interesting to see a juxtaposition of the many variations (say, 100 screen shots) in one big image.
Structure #003B
A surface filled with one hundred medium to small sized circles. Each circle has a different size and direction, but moves at the same slow rate. Display the aggregate intersections of the circles.
