Show HN: Psychedelic animation generator; (p)art of your next trip https://ift.tt/imtNKw6

Show HN: Psychedelic animation generator; (p)art of your next trip Sharing an open source project for creating psychadelic art -- using liquid motion, distorted shapes, shadows and light. This tool works in real-time in the browser using webgl shaders. This project was inspired by drum & bass / acid techno music, and 90s rave posters. Use this to create art for a music video, concert posters, stylized animations in creative projects, or simply to enjoy alongside some fine music. Use the detailed control menu (top-right) to set a custom canvas size, adjust animation speed, control pattern and colours, etc... You can export your creation as an image or video afterwards. How this works: this tool uses WebGL shaders to create a real-time animation (with a trippy liquid / shadow / blur aesthetic). The animation is created using a random seed position and mixes in random noise (fractal brownian motion, 3D simplex noise), so each time you re-run it you're creating a unique piece of art. Github repo: https://ift.tt/4sz5p0n ----- I hope you enjoy the visuals. I'd love to hear any feedback or suggestions. https://ift.tt/7GUrySR March 14, 2025 at 04:56AM
