Flex resources
If you are interested at all in Rich Internet Applications (RIA), then you might want to get familiar with Adobe Flex. Flex is an xml tag language similar to xhtml. You write your tags and optionally actionscript 3 which then all gets compiled down to flash 9. It is pretty easy to use and there is a nice IDE called Flex Builder from Adobe.
Some great examples can be seen at Adobe's website; the Component Explorer is a great way to see what some of the code looks like and also see what components you get "right out of the box". There are other resources available like the Style Explorer to check out as well. So have fun developing RIAs with Adobe Flex.
p.s. Flex consumes xml very nicely, so anything that produces xml can be a datasource for flex. I use Ruby on Rails of course for my development. There are also some very nice tie ins with ColdFusion if you happen to have that available as a resource.
