Spark Application background in Illustrator trough Flash Catalyst

Today I want to propose you a short video tutorial to introduce Flash Catalyst and graphic object.

I propose you to build a simple background for your Flex 4 application in Illustrator.

To begin, a poll to know which Flex version you use

That is a question I’m trying to answer.

What is the best to use for a personal project when you want a well designed application.
