I got to know about Aviary through a colleague. I looked at their site and realized, they have some amazing tools (Flex/AIR based), which are editors/generators for image, vector, 3d, video, audio etc. As mentioned, these tools are web-based (flex) and desktop-client (air).
I am yet to look at their tools which are accessible only on invitation. I hope, I would get an invite soon. Why don’t you check it out too?
This is one more example to show why entire flash/flex ecosystem is so cool.
