Speaking of JavaScript ...

... I just came across LabPixies. They have a bunch of Google Gadgets (they also work with other Web 2.0 sites) that appear to be written entirely in JavaScript.

Some of these are really cool and must really push the boundaries of what can be done with JavaScript. Unfortunately, they are closed source, so you can't (easily) figure out how they do it. I recommend checking it out just to see what some people are doing with JavaScript and Web 2.0.
