guizang shared a Qimen Dunjia divination learning site built with Claude Opus 5.5. Started as a toy project, it drew real demand, so he added exercises and explanations to make it a proper learning site.

He also joked that designers obsess over details in unexpected places: the About page compass was rebuilt in 3D with rich detail, and the needle rotates to follow your mouse — a classic case of an AI coding side project drifting off-scope.
