This made curious what patterns emerge when the objects move along circles instead. So I made this 10 minute hack to simulate it: http://www.gibney.org/spiral_

Very pretty. It's a lot less crowdy if you change line 105 in your script to var speed =(nr_elements - i)/1000;

  Yeah, then the inner objects move faster and the outer objects move slower. I find it hard to say, which version I prefer.

    Physics prefers that change, at least when gravity drives the motions. If you adjust the periods as distance^1/3, you get a simple model for a solar system.

This version is nice because it's even clearer what's going on at integer-divisor points in the process, with different numbers of "arms" on the pattern.

  Wow, it is beautiful. I'm trying to wrap my mind around the scheduling and the scale. It looks like it's calibrated to run an entire cycle in an hour, so if you see 6 arms (say) at the center, it's been running for 1/6 of an hour. I'm trying to grok how the outward propagation works. It seems that a structure at the core propagates outward, while the core reorganizes itself into the next integral division (say 1/5). So you can get 5 arms at the core and 6 arms near the outer edges at the same time. Check out this capture image. 4-way symmetry at the core, 5-way symmetry in the clusters halfway out, 6-way symmetry (faint but recognizable) at the outermost edge. http://www.dos486.com/misc/spiral-clock.gif http://www.dos486.com/misc/spiral-clock.gif You also get recognizable structure for non-integral divisions, say 2/5. These structures are shorter-lived because each element is passing by an element two spins away instead of one so they converge and diverge faster.

Interesting visual side-effect: watch the spiraling to completion, then flip back to HN and watch the text swirl.
