Kool Brushez is a p5.js drawing app with six independent brushes: Score draws flowing musical-staff ribbons, Schematic creates drafting diagrams, Balloon reveals airbrushed shapes, Subway generates branching transit lines, Crowd draws animated people, and Gunpla grows model-kit sprues. All brushes use one shared canvas, so users can switch between them without reloading or losing existing marks; each brush has its own JavaScript drawing algorithm, settings, preview, and registry entry. The app provides brush-specific controls, auto-fill and variation modes, undo and redo, erasing across brushes, aspect-ratio fitting, keyboard shortcuts, touch and pen input, and PNG export. It is built with Vite, plain JavaScript and CSS, and is released under the MIT License.

Sprite Studio is a local-first, open-source desktop AI workbench for creating, animating, testing, organizing, and exporting 2D game art. It combines prompt- and reference-based generation with pixel-scale review, sprite viewing, animation planning, loop testing, rigging, deterministic rendering, and PNG sprite-sheet export with metadata. For animation, the AI plans a complete motion sequence and generates frames sequentially using the source asset's identity and neighboring accepted frames. Its native Rust rig engine uses named joint, anchor, contact, and pivot points plus capsule bones; it assigns opaque pixels to bones, supports planted contacts through analytic two-bone inverse kinematics, and renders frames through bone transforms and nearest-neighbor inverse mapping without image generation. The resulting frames flow into asset organization, quality analysis, the playground, and exports. The application runs on macOS, Windows, and Linux and is built with Tauri, Svelte, Rust, SQLite, and an installed Codex CLI. It is designed for local-first use and does not target Android or iOS.

ReelMimic is a local 2D animation tool that uses Claude Code or Codex to create a new video from a reference video and a brief. It analyzes the reference's shot count, pacing, BPM, transitions, framing, colors, and camera movements, then produces a storyboard, character and asset plan, and style frames for approval. After approval, multiple AI agents build different parts in parallel, while separate agents review completed shots and request fixes with before-and-after screenshots. The tool supports seven drawing engines: vector/motion graphics, hand-painted watercolor, crayon picture book, pixel art, paper cut-out stop-motion, whiteboard doodle, and anime cel; new styles are defined in Markdown. It runs on the user's computer, uses the user's Claude Code or Codex account, and does not reuse the reference video's footage, characters, logos, or assets. The repository is MIT-licensed and has been tested primarily on Windows, with macOS and Linux support described as less tested.

genart-skill is a Claude Code plugin that provides an AI coding skill for generative art. It teaches deterministic, hash-seeded compositions, including seeding a pseudorandom number generator from a token hash, using named sub-streams, rendering the same composition at different resolutions, and designing traits and rarity tables for editions. It covers Canvas 2D, p5.js, Three.js/WebGL, and SVG, with guidance on ethics, platform-specific workflows, debugging, keyboard shortcuts, PNG and video export, and print and pen-plotter output. The plugin includes scripts for checking same-machine repeatability, distinctness, global-state isolation, and feature stability; rendering a hash-specific PNG or contact sheet; measuring rarity across a census; and exporting batches of images. The scripts can be run in a project and use Playwright when browser rendering is required. The repository explicitly limits its determinism claims, noting that GPU shader compilers, floating-point behavior, rasterizers, MSAA, and JavaScript engines can prevent cross-machine equivalence. It is installed through the Claude Code plugin marketplace and is maintained by Camille Roux. The repository says that CI tests the scripts against a known-good fixture and a deliberately broken variant, while a monthly check verifies that platform-documentation URLs still resolve. It is licensed under the MIT License.

Krbn, pronounced “Carbon,” is an open-source TypeScript web engine for non-photorealistic, pencil-style rendering of 3D scenes to SVG. It is intended for abstract and technical scenes, with medical and organic illustration described as a future direction. Rather than rendering surfaces as pixels, Krbn derives, classifies, and styles strokes from geometry. Its analytic primitives produce exact silhouettes such as conics and the true quartic of a torus; hidden lines are split into visible and ghosted runs; intersections are solved using low-degree polynomial roots; and triangle meshes pass through the same rendering pipeline. Hatching provides shading and transparency through stroke density and direction, including curvature-following patterns such as sphere parallels and meridians, torus loops, and streamlines on arbitrary meshes. Scene semantics such as importance, focus, and role guide what the engine draws, ghosts, or abstracts. The pipeline includes hidden-line visibility, suggestive contours, hand-drawn wobble, and variable-width strokes. Wobble is seeded from stable stroke identities so animated camera movements do not cause the lines to boil between frames, and the project aims to emit deterministic, byte-identical SVG on a given platform. It supports scene and animation construction through an API, with examples including STL and OBJ imports and an animated camera orbit. Krbn is MIT-licensed.
