Example Configurations

The 68 runnable configurations that ship inside the package. Run one with c64cast --config example:NAME, or copy it out to edit with c64cast --print-example NAME > c64cast.toml. Each summary is read from the file's own header comment.

The Demos#

A demo tagged needs your own media points at assets/, which ships empty because the material would be somebody else's. Drop a file in or repoint the scene's file before running it.

Name	Description
`audio-reactive-input`	generative visuals driven by LIVE AUDIO INPUT.
`audio-reactive-listen`	generative visuals driven by LIVE AUDIO INPUT, with NO C64 audio output — the "listen-only" VJ case.

`color-dither`	spatial dither ([color].dither) on a slideshow. (needs your own media)
`color-force-palette`	the EXTREME forced-palette remap ([color].force_palette). (needs your own media)

`effect-reactive`	a MUSIC-REACTIVE pixel effect over a generative source + SID-file playback.
`effect-trails`	a per-scene pixel EFFECT layered on a generative source.

`overlay-weather`	PETSCII webcam + weather overlay.
`performance-clips`	Clip-launch grid demo (Live DJ/VJ Phase 2): fire scenes from a MIDI controller, quantized to a musical beat grid — a "video sampler" in the spirit of a Roland P-10.
`scene-asid`	ASID stream → real SID + oscilloscope.
`scene-blank`	blank PETSCII canvas with a big_text overlay.
`scene-generative-colored-bursts`	"Colored Bursts" — a WLED-effect port.
`scene-generative-dna`	"DNA" — a WLED-effect port.
`scene-generative-dotswarm`	"Dot Swarm" — a WLED-effect port covering the shared shape of several kin effects: a handful of points, each independently orbiting via a bounded sine at its own frequency, color-cycled and blended, plus a fixed white center dot (Black Hole's signature).
`scene-generative-drift`	"Drift" — a WLED-effect port.
`scene-generative-epicycle`	a Fourier epicycle chain (circles spinning around the tip of the previous circle) rendered as a multicolor bitmap.
`scene-generative-fire`	a generative FIRE source paired with SID-file playback — the most viscerally music-reactive generator.
`scene-generative-fireworks`	"Fireworks" — a WLED-effect port of WLED's shared particle-system engine's flagship preset: shells launch, arc under gravity, and explode into a fading burst of particles.
`scene-generative-game-of-life`	"Game Of Life" — a WLED-effect port of Conway's Game of Life on a coarse grid, with WLED's signature "parent color inheritance": a newly-born cell's color is the blend of its live parents'.
`scene-generative-halo`	several soft-edged halos drifting on independent orbits, additively blended (bright where they overlap), rendered as a multicolor bitmap.
`scene-generative-hiphotic`	"Hiphotic" — a WLED-effect port.
`scene-generative-hopalong`	the Hopalong chaotic point-map attractor (Barry Martin's `x' = y - sign(x)sqrt(\|bx - c\|)`, `y' = a - x`) rendered as a multicolor bitmap.
`scene-generative-lissajous`	"Lissajous" — a WLED-effect port.
`scene-generative-mandelbrot`	a procedural Mandelbrot zoom rendered as a multicolor bitmap.
`scene-generative-metaballs`	"Metaballs" — a WLED-effect port.
`scene-generative-moire2`	a moiré interference pattern rendered as a multicolor bitmap.
`scene-generative-petscii`	the SAME plasma source as scene-generative-plasma.toml, but rendered as PETSCII glyphs instead of a multicolor bitmap.
`scene-generative-plasma`	a procedural plasma rendered as a multicolor bitmap.
`scene-generative-rorschach`	a mirrored-symmetric ink-blot rendered as a multicolor bitmap.
`scene-generative-rotozoomer`	"Rotozoomer" — a WLED-effect port.
`scene-generative-sid`	a generative plasma paired with SID-file playback — the headline of the composable building blocks.
`scene-generative-soap`	"Soap" — a WLED-effect port of a persistent color buffer smeared/advected each tick by a slowly-rotating noise-driven flow field — the classic swirling soap-film look.
`scene-launcher`	launch a native C64 program (game or demo) on the U64 and hand the machine over to it. (needs your own media)
`scene-midi`	MIDI → SID synth + oscilloscope.
`scene-slideshow`	cycle through still images on the C64 display. (needs your own media)
`scene-video-sampler`	video playback with HIGH-FIDELITY audio via the U64's "Ultimate Audio" FPGA PCM sampler (instead of the lo-fi 4-bit $D418 DAC). (needs your own media)
`scene-video`	video file ("video") playback with audio. (needs your own media)
`scene-waveform`	SID playback ("waveform" scene). (needs your own media)
`scene-webcam-audio`	webcam → PETSCII + live mic through the SID DAC.
`scene-webcam-hires`	webcam → hi-res bitmap mode.
`scene-webcam-hires_edges`	webcam → hi-res bitmap with Canny edge detection.
`scene-webcam-mcm`	webcam → multicolor character mode (MCM).
`scene-webcam-mhires`	webcam → multicolor hi-res bitmap (MHires).
`scene-webcam-petscii`	webcam → PETSCII char mode.
`scene-wled`	the C64 as a virtual WLED LED matrix (WLED bridge Mode 2).
`teensyrom-blank`	the TeensyROM+ backend driving a blank canvas with a scrolling-text overlay over USB serial.
`vision-gesture`	webcam hand-gesture control (the vision controller).
`vision-modes`	Vision demo: SWIPE cycles the video MODE; hold-open cycles the style within a mode; pinch pauses.
`wled-control`	Control c64cast FROM the WLED app (WLED bridge Mode 1 — "listen"). (needs your own media)
`ensemble/left`	Per-system config for the leftmost screen in the ensemble.
`ensemble/master`	Master config for a 3-system ensemble (a row of three Ultimate 64s laid out left → middle → right, viewed from the front).
`ensemble/middle`	Per-system config for the middle screen.
`ensemble/right`	Per-system config for the rightmost screen — also the conductor for the cross-system big_text broadcast (since the message scrolls right-to-left, it enters on the rightmost screen).
