Developer creates interactive ASCII donut

Original: ASCII Donut Math Animation — 30 Days Web Challenge Day 2

Short summary

A developer implemented an interactive ASCII donut animation as part of a 30-day web challenge, bringing the classic donut.c algorithm to the browser with mathematical torus rendering, z-buffering, glitch effects, sound synthesis, and particle animations. Code demonstrates real-time character grid rendering and Web Audio API integration.

  • Mathematical torus renderer using sin/cos projection with z-buffering for depth sorting and luminance mapping
  • Interactive glitch mode triggered by clicking, with randomized rotation offsets and character scrambling
  • Particle explosion animation and sound synthesis using Web Audio API after 5 clicks

Generated with AI, which can make mistakes.
