howtoons.com on CNN this morning at the gym. In their own words:
Howtoons are cartoons showing kids of all ages "How To" build things. Each illustrated episode is a stand-alone fun adventure accessible to all. 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.
Much like MIT has OpenCourseWare distributing curricular materials for college students worldwide, our Howtoons are OpenKidsWare, with practical build-it projects letting kids learn-by-doing, MIT-style!
So far not a lot of videos, but this morning they only 5 and now they're up to 7. Extrapolating, they should have 30 by the time you click through.
