Principles of Play
summary
A children's book and workshop series called Hello Ruby grows from a Rails Girls seed that reached 227 cities and a Kickstarter that raises $380,000 (over $100,000 in 24 hours). It distills three actionable principles — playfulness, rules, curiosity — and ships free exercises and hands‑on workshops where kids build mock CPUs and RAM, design apps (dolphin health, mission control), and prototype printed Legos, showing concepts as tangible rules and surprising possibilities.
