- GLSL learners and creative-coding hobbyists
- Worth noticing
- The comparison interface offers split, swipe and difference views, and the basics course is described as six short lessons.
Field notes
The play screen exposes a target-versus-your-shader comparison, with split, swipe and difference views, plus a timer, up to three hints and a lock-in action. The editor offers GLSL and node-based creation, surface-pixel or shape-vertex modes, and mesh choices including sphere, torus knot, cube and plane. A six-lesson basics route covers colour, normals and light; gallery publishing asks for GitHub or Google sign-in.
