This looks interesting. Itzabitza is Windows-based drawing software that automatically creates animations out of (carefully scripted) drawing activities.
We'll look into reviewing it - Z is a drawing fool these days, and loves "working" on the computer, too. The success of this software (developed in partnership with Microsoft) will come down to how proscriptive it is vs. how well it can interpret and accept kids' wacky drawing styles without judgment (or the implied judgment of aborting the animation mission based on the drawing).
You can pick up a copy for $15 from Amazon.com if you can't wait for our take on it. - Jeremiah
