Some bright Spark…
Now then, if you're not aware of the Spark project, you're missing out.
It's a large open-source community of Flash / ActionScript developers based in Japan. Their SVN repository is bursting with experimental and innovative code - it's the birth place of the FLARToolkit which you will (probably) of seen used for a bit of augmented reality, like this and this.
There are many interesting things hidden away in the extensive ( 800-900Mb if you check it all out ) SVN repository, and it's well worth a browse if you have a spare moment or two... you're almost guaranteed to find something inspiring lurking in the depths.
Not unlike this high performance tweening engine. Huzzah, another tween library(!), I hear you cry. But it looks fast and feature filled. Be sure to check out the speed comparison demos (and scroll down the page for a few more interesting projects hosted on libspark)
Ooh, now this is not from the Spark project, but it is rather nice. Check out a retro-tastic 64K demo for FlashPlayer 10
