Topo Lines
Draws contour lines through the layers below, like a topographic map of their brightness
The lines on a hiking map join every point at the same height: crowded where the ground is steep, far apart where it is flat. This does the same to the picture beneath it, reading light as high ground and dark as low and drawing a line at each level. Over noise you get a terrain map out of nothing; over blurred type the lines ripple out from the letters as offset outlines; set them travelling and they flow through the levels like rings spreading on water.

II. Everything else
- Blob Tracker — Locks targeting marks onto what moves below
- Contour — Detects edges with a Sobel filter and draws them as clean outlines
- CRT — Puts the layers below on a tube screen — scanlines, phosphor and curved glass, or worn VHS tape
- Dither — Ordered dithering of the layers below (duotone or reduced color)
- Glitch — Row displacement and scanline injection
- Glyph Dither — ASCII/glyph rendering of the layers below, by brightness
- Grain — Film grain noise, optionally animated
- Halftone — Rebuilds the image as a rotated grid of ink dots, lines or squares
- Pixelate — Snap coordinates to a coarse block grid
- Posterize — Quantize luminance into a flat color palette
- Subdivide — Break the layers below into blocks that keep splitting, by chance or by detail
