BrandLoom: Project Logos & Covers
Need a logo and cover that feel like they belong to the same project? BrandLoom helps you turn your project idea into a clear, consistent visual set. It reads the project information, files, links, and brand materials you provide, then asks one simple question at a time. You choose the wording, style, fonts, characters, layout, language, and image size before anything is created. BrandLoom can make a square project logo image, a wide cover, and a GitHub social preview in Chinese, English, or both. It can reuse your existing company logo and approved brand assets, keep important text clear, save new versions without replacing old ones, and help with later edits, translations, and style changes. It is made for solo founders, indie developers, AI builders, creators, and anyone launching a GitHub project, Skill, app, or digital product. Made for Codex. Full image creation requires Python 3.12 or newer and access to Codex's built-in image tool.

An imaginary cursor crosses the surface; nearby tiles respond to its Gaussian depth field with lift and tilt, and only the cells intersecting either headline silhouette turn over to reveal the rear headline. The whole grid is one instanced WebGL 2 draw with a shared front/rear texture pair, plus a batched projected-shadow pass. Copy, text size and square cell size are independent, so tiles never stretch. Sweep direction, easing stre
