Yi-Yi open-sources Teachable Figures, an AI agent skill for interactive lessons

Yi-Yi, a solo developer posting as @yiyibuilds, has open-sourced Teachable Figures, a skill that lets AI agents build interactive 2D and 3D lessons.

The author says the lessons support Chinese and English and can run offline. Demo topics include Transformer attention, chest anatomy, rocket structure, cone cross-sections, a Ming-dynasty robe, and gear ratios. Each lesson follows a predict, try, observe, explain, apply sequence. The project builds on Anatomy and iso-figure rendering work, which the author credits.
