Jon Udell linked to some screencasts by Peter Wayner, and their are a couple of toolkits reviewed that I had not looked into yet. Their is rico that I had never heard of before, the zimbra kabuki toolkit, which I didn't know existed, even though I know and have seen zimbra in action. And Google web toolkit, which I had heard of but never seen in action (not really a java fan, so never bothered to look). Anyways, here is a cool way to learn about more javascript toolkits!
