Upon it's release, Z has been evaluating the software for use in upcoming animations and artwork after falling into limbo on what to use when Macromedia's Flash was brought by Adobe. With tutorials popping up all over YouTube nearly a day after it's release, the initial high learning the software was quickly lowered.
