Some fun links for kids:
Incredibooks has book reviews for kids, written by kids (and probably a few creepy middle-aged men).
Story Nory makes iPod ready, free narrated kids tales. Pass long car rides with these fairly tales and modern classics. Also some good reviews in the archives.
PBSKids has games, stories, and music based on the programs.
Learn to Draw with these instructional books. The whole books are free on-line.
Also, look at this trippy alphabet clip. Think this is from the 70s?
Thanks to Chris Watk for the pic!
