SPIROW: Post-Colon

The simulation is of how it would look at night, obviously. The arms won't be lit, so aren't being drawn.
The lights will be quite bright; each will be the equivalent brightness of roughly 24 lightbulbs when fully 'on', or 8 lightbulbs when a primary colour, or 16 when a secondary colour. This is obviously not captured well from your monitor, which is not as bright as even a single lightbulb. Nor is the scale captured.
Some of these seem to be going around pretty fast; bear in mind that 1 hz means the big wheel is going around ONCE per second, not a lightning-fast rotation.
Some of these work at different gearings; one fixed gearing is quite easy to use, and multiple gearings could be a challenge. I'm hoping it'll be possible, but I can't guarantee it.
Source code (so you can confirm I'm not cheating!) is available here.

Programs (all hz approximate)

0: 0.75hz, gearing 3:1, three bundles lit.
1: 1.5hz, gearing 2:1, three bundles lit.
2: 1.5hz, gearing 2:1, nine bundles lit.
3: 1hz, gearing 1:1, six bundles lit.
4: 1.5hz, gearing 2.5:1, twelve bundles lit.
5: 0.75hz, gearing 2:1, nine bundles lit.
6: 1.5hz, gearing 3:1, eighteen bundles lit.
7: 1.5hz, gearing 3:1, twenty-seven bundles lit.
8: 1.5hz, gearing 2:1, twenty-seven bundles lit.
9: 3hz, gearing 2:1, eighteen bundles lit.
10: 3hz, gearing 2:1, nine bundles lit 1/3 of the time, none the rest.
11: 0hz (simulating some kind of malfunction), gearing doesn't matter, nine bundles lit.
12: 1.5hz, gearing 2:1, daytime operation (give or take).
