It was only the other week, setting up my mom's new PC, that I realized Firefox 2 is out. I'd recommend it for everyone. From my perspective, the biggest improvements are how ctrl-F now searches textareas and every input form has built in spellcheck with red underline! I was using Google's toolbar spellcheck for that functionality, but having it happen without having to remember to click is a big win.
So many great details, like how you can watch the creation being drawn in, or how the central dancer is surrounded my a giant crowd of clones... Make your own and post the # or link in the comments!
