Gravity Feedback

Last frame swells, spins and drifts back through itself until the picture starts generating its own.

Runs live on video, images, a camera or generated art. Stack it with any other effect, and route LFOs, envelopes or any of ten audio bands to its controls so it moves with the music.

Controls

Zoom
How much the held frame swells or shrinks each pass. Centre is still.
Rotate
Spin per pass. Combined with zoom this is what makes the spiral.
Drift X
Sideways travel per pass, which throws the spiral off centre.
Drift Y
Vertical travel per pass.
Sustain
How long trails hold. High enough and they stop fading at all.
Bloom
Gain inside the loop. Past halfway the feedback sustains itself into reaction-diffusion.
Hue warp
Hue bend per pass. Tiny amounts walk the whole wheel over a second of feedback.
Overflow
What happens to signal driven past white.
