- Grow
- Whether the held frame swells or shrinks each pass. Centre holds still, either side sends the filaments travelling.
- Spin
- Turn per pass, which curls the breeding rings into spirals instead of even shells.
- Sustain
- How much of the held frame survives each round. Past centre the nest stops decaying and keeps thickening.
- Bands
- Contour rings across the accumulated bloom. Low is a few travelling shells, high is a dense nest.
- Tint
- Rotates the whole rainbow around the wheel.
- Cycle
- Hue step per ring. Low spreads one rainbow over many rings, high gives every ring its own colour.
- Glow
- Light falling off the strokes. Hard left is a bare filament, up high each one blooms into the frame around it.
- Speed
- Rate of the effect motion. Centre is the authored speed, hard left a tenth of it.
