Peekaboo Forest. Notable for incorporating Charley Harper's artwork. (Although beautiful, my 2.5 son found this app too slow and the animals too small to easily touch). One to watch: developer Night and Day Studios is currently at work on an app using Richard Scarry art! • Intro to Math, Intro to Letters and Alpha Write by Montessorium. "Old School Meet New School" • My Very First App uses Eric Carle's universally loved artwork in a matching colors game. • HappyBaby app uses fruits and vegetables to learn the alphabet (they even found something to represent "x"). • ABC: Look. Listen. Write. featuring funky art by DP Sullivan. • Paper Town Friends: quite possibly the cutest app ever. Young toddlers may need help putting outfits on these paper friends, but they'll have fun choosing what they should wear. • Fans of Todd Parr's books will want to check out the My Underwear app.
