Use cases

Where it fits

Landing heroes

ASCII kaleidoscope loops power the Reeldemo org page and product promos — same engine, browser and CLI.

Social ads

Export HTML or ANSI from stills. Match color schemes to brand palettes without a motion graphics pipeline.

Terminal art

Sub-millisecond Rust renders at terminal scale. Drop an image, tune segments and rotation, ship.

npm pipelines

Engine

Under the hood
