I am currently working as a UI designer at a larger software company, building our application interface with HTML, CSS and Javascript. I want to explore the possibility of developing UI on the Flash platform for various reasons. Has anyone here made the transition? How have you made the switch? How steep was the learning curve? Were you able to present some of your ideas in Flex in a relatively short periond of time? Before doing anything, would you recommend any learning materials for a quick start with Flex? Thanks so much in advance for sharing your experience.
