Must check this out in more detail when I have the time:

bq. “Howtoons”:http://www.howtoons.org/ are one-page cartoons showing 5-to-15 year-old kids “How To” build things. Each illustrated episode is a stand-alone fun adventure accessible to all, including the pre-literate. Our Howtoons are designed to encourage children to be active participants in discovering the world through Play-that-Matters — fun, creative, and inventive — and to rely a lot less on mass-consumable entertainment.
