Flex Open Source Fisheye Menus Component From Quietly Scheming
The Fisheye component is based around the concept of itemRenderer factories, just like the flex list and charting components. The goal is to use composition to separate behaviour from content, so you can reuse the basic fisheye effect across many different applications and uses. It???s available under the MIT Open Source license, so feel free to use it or modify it in your own applications. Check out the 2D Fisheye Demo, it looks really nice.
Quietly Scheming has many other components over there.
