- Animator offers more fine-grained control over animation curves, beyond hard coded curves like "Ease-in, Ease-out"
- Animator is entirely focused on CSS3 animations, there's very little opportunity for making interactive content beyond "click to advance to the next scene"

With Animator, we've tried to minimize the distance between what you do in the tool and what you'd do with hand-built animations. This means that the outputted source is relatively easy to tweak as you see fit. Animations can also be fitted relatively easily into your existing page source by specifying classes etc.
When you nest an animation, for example, you're nesting a DIV under the covers. You can manually set z-indices, so the animation doesn't blow up the rest of your page. You can manually enter rgba colors into the color pickers etc.
Some other things about Animator - nested animations. Nesting is a really key tool to have - you can do some brilliant animations without a lot of work with nesting.
That said, it's great to have another entrant in the HTML5 animation category. Welcome to the party Tumultco!
