Today I experimented with Fuse and Flash. Fuse is a sequencer using ZigoEngine written in ActionScript for performing Tweens/Animation using code. Best thing about Fuse is that you can predefine sequence of animations in code and all will be handled. And using ZigoEngine it just becomes very optimal on CPU and RAM. Look at the following example and checkout your CPU usage, it doesn't hike. In some of my next examples I am going to showcase some of the cool uses of Fuse.
