Here is the first review for Richard Williams new iPad app based his The Animator’s Survival Kit. If you don’t have an iPad, you may even consider buying one just for this app alone. It’s that good.
Available now for the iPad (sorry iPhone, Android, and others), this app is an ABSOLUTE MUST HAVE for any animators with an iPad.
It’s definitely worth checking out. Not only is it the book, in an oh-so-portable version, but it also has animated examples, for you to scrub through an examine.
