ttfx is a dependency-free Rust command-line tool that applies terminal text animations to piped input and distributes them as a single static binary. It is a parity-exact port of the Python TerminalTextEffects project, preserving its effects, animation engine, command-line interface, cursor behavior, options, and implementation quirks rather than introducing new artwork. Users select effects such as decrypt, beams, matrix, or a random effect with commands such as `cat banner.txt | ttfx beams`; the project documents 37 effects and byte-identical output to the Python original for the same input and seed. The port and original are MIT licensed.

rataflow is a Rust library for building interactive node-based user interfaces in the terminal, from static diagrams to editable graph views. It is built on ratatui and inspired by xyflow (React Flow). The library provides generic nodes and edges, parent-child hierarchies, configurable interaction flags, dragging, resizing, connection and reconnection, selection, pan and zoom, keyboard navigation, context-menu events, connection validation, and automatic edge-of-canvas panning. It renders custom node and edge content, includes built-in edge types and companion widgets such as controls, a minimap, and a background, and supports runtime palettes and layered Sugiyama layout. Graph snapshots can be serialized with serde, while handlers return semantic FlowEvent values without hidden graph mutations. Input backends include crossterm, termion, termwiz, and WebAssembly through ratzilla; the project also provides browser examples compiled to WASM.

Shitty is a terminal emulator for macOS and Linux/Wayland, built for low latency, fast startup, and predictable resource use. It keeps terminal state on the CPU and renders changed cells with native compute backends: Metal on macOS and Vulkan on Linux. It supports VT52 through VT5xx and ECMA-48 controls, ISO-2022 character sets, common xterm extensions, primary and alternate screens, scrollback reflow, hyperlinks, shell marks, mouse and keyboard input, resizing, HiDPI and fractional Wayland scaling, and Unicode 17 grapheme clusters including emoji sequences and wide CJK characters. Resize frames are rendered in the same transaction as bounds changes, and updates are damage-driven. The project provides native macOS and Linux/Wayland frontends as a small self-contained binary with embedded fonts. Its README describes more than 5,000 black-box tests driven through a real PTY, a fuzzed parser state machine, and a default security model that prevents applications from reading selections or controlling the host window unless explicitly permitted. The same terminal code is also distributed under the user-facing name Pretty.

Shrimply is a free, open-source video editor for creating videos from start to finish. Its main application is written in Rust with a GTK 4 and libadwaita interface; rendering uses Skia, wgpu, Slang, and CUDA, while FFmpeg and PipeWire handle media and a Python component provides the compute server. The project is pre-alpha software and warns of undocumented footguns, performance regressions, irreversible project-file breakage, crashes, resource leaks, and security limitations. It is licensed under GNU GPL version 3 or later, although some features depend on separately licensed NVIDIA components and model weights.

Ember is a collection of redshift-aware color palettes for terminals, interfaces, charts, and heat maps. It models warm-screen filters at 3400 K, 2000 K, and 1200 K, where each RGB channel is multiplied by a different gain, and supplies palettes designed to preserve text readability, categorical color separation, contrast, perceptual separation, and ordered lightness after the modeled transform. It includes neutral or warm-neutral text and surface colors, terminal accents, categorical palettes, and 256-sample sequential maps; deeper filters intentionally provide fewer distinct semantic colors and may assign unsupported ANSI names as aliases. The palettes are distributed in terminal, CSS, JSON, Python, and Matplotlib formats. The repository documents deterministic filtered-output simulations based on published gains rather than photographs, calibrated physical color temperatures, or predictions of every display pipeline.
