# [Light Rails]() Generative light-pattern studio with 38 shape families, colour templates, live brand mockups and PNG, GIF, WebM and MP4 export. Free·generative·Patterns·Light Trails·Mockups Free·generative·Patterns·Light Trails·Mockups ![Light Rails preview 1]() ## What is Light Rails? Light Rails is a free, browser-based generative pattern studio built by designer Dinesh Subramani. A WebGL canvas renders light-trail patterns from 38 shape families, from perspective fans, spirals and concentric rings to petal bursts, glass planes, ASCII rain and typed-digit contours, each driven by sliders for flow, line count, warp, flare, ribs, grain, bloom and dwell time. Colour orbs and named templates such as comb-fan, pinwheel and cosmos set the palette, and a UI overlay wraps the running pattern into editable brand mockup cards for a reel. Work can be saved as a PNG still, a JSON settings file, a WebM or MP4 clip recorded off the canvas, or a short GIF, with undo, redo and history built in. ## Features - 38 shape families across fans, beams, rings, tunnels, flowers, fields and solids - Colour templates and gradient stops applied over a live WebGL canvas - Slider stack for flow, lines, warp, flare, grain, bloom and motion timing - Draggable custom-path shapes (Shape shifter, Trail) and typed-digit rails - Live UI mockup overlay that wraps the pattern into card and brand layouts - Export as PNG still, JSON settings, WebM or MP4 clip, or 3-second GIF ## FAQs Common questions about Light Rails What can I export from Light Rails? The Export menu offers a PNG still, a JSON file of the current settings, a WebM or MP4 clip recorded straight from the canvas, and a 3-second GIF. MP4 depends on the browser having an H.264 encoder. Is Light Rails free to use? Yes. The studio runs in the browser with no sign-up or pricing. The maker accepts optional support through PayPal or UPI from the Roadmap panel. ## Ask AI about Light Rails ## Share --- Canonical source: https://creatorstoolbox.com/tools/light-stroke-rail
