Compositing node
Trails
Two related nodes that feed a frame back into itself with a slight zoom, spin, or fade — the same trick behind classic video-feedback tunnels. Every new stroke or shape leaves a trail that spirals off into infinity.
What it does
Trails is a compositing node: it layers, masks and routes pictures. It takes picture in and gives picture out.
Try it
Paint one stroke on the Draw canvas and watch Feedback turn it into an endless spiral.
