Flex

Critical Mass uses a lot of flash. I don't know anything about flash. So yesterday, while I was reading the Rich Internet Application (RIA) wiki page, trying to learn more about RIAs and flash, I found this link. It's very very cool stuff, much like the album cover viewer in the latest major release of iTunes. Adobe has an Eclipse-like development environment you can download and create your own Flex applications. I'm gonna try it.
