Free Tool For Creating Flash Animations: Giotto
Flash is losing blood, that's for sure and there is a chance that you may have already quit using it. However, it is still the most powerful platform on creating animations for the web and there can be cases that we need it.
Giotto is a free tool (Windows-only), focused on designers rather than developers, for creating Flash animations easily.
It has a Flash-like but a little simplified user interface that helps you feel comfortable using it with ready-to-use effects, ability to draw or import shapes and built-in animations (all without coding).
If you prefer to dive into ActionScript code, there is support for that too (but sadly, only AS1 and AS2)
