9 effects to finish the look
Effects run after the grid is drawn, in a fixed order, and stack freely. Time-based ones — scan lines, grain, glitch and dust — move with the Motion clock, so they animate in GIF and video exports.

VignetteDarken the corners to pull the eye to the centre.

Scan LinesHorizontal lines and a rolling bright band, like an old monitor.

ChromaticSplit the image into offset red and cyan copies.

BloomMake bright glyphs glow into the dark around them.

Film GrainMoving monochrome noise, like photographic film.

GlitchDisplaced slices and colour bars, like a corrupted signal.
PixelateDownsample the finished frame into big square blocks.

HalftoneA newspaper dot screen over your image.

Film DustSpecks, hairs and scratches, like projected film.
