## What it is
tachyonfx is a Rust library providing shader-like effects and animations for Ratatui terminal user interfaces. It offers 50+ composable effects with spatial patterns, cell-precise targeting, and WebAssembly/no_std support.

## Use cases
- add fade-in animations to a Rust TUI
- create terminal text effects like dissolves and sweeps
- compose layered animations in a ratatui app
- run animated terminal UIs in the browser via wasm
- apply shader-like visual effects to terminal widgets

## When to choose
- you're building a Ratatui-based TUI and want polished animations
- you need composable, cell-targeted terminal effects
- you want effects that also run in wasm or no_std environments

## When to avoid
- your TUI is not built with Ratatui
- you need GPU-accelerated graphics rather than terminal cell effects
- you want a full TUI framework rather than an effects layer

## Facets
- artifact type: library
- maturity: active
- function: animation, ui-components, graphics
- domain: developer-tools, graphics
- platform: rust, cross-platform, wasm, cli
- tags: ratatui, tui, terminal-effects, shader-like, tweening, no-std, command-line
