Try Flex Online!
October 29, 2006 ·
Ben Forta (with a little help from some of his friends) has created The Flexifier - a website that lets you enter MXML and AS3 and see what it does. It's built with Flex and ColdFusion and Spry and will let you experiment quickly with Flex without needing to download anything. Apart from being a useful educational tool, it's a lot of fun!
