GoASAP: The Go ActionScript Animation Platform
It’s a versatile, generic base library for building animation tools in ActionScript 3.0.
Go provides the tools to build the tools. It enables developers of all skill levels to do build those tools rapidly, even ones not possible with today’s tweening packages. Think of it this way: where all other systems on the market today are top-down, Go is roots-up. (There are some other goals as well, such as providing compatibility between systems, but I won’t bore you with that now.)
