[EDIT: Can't edit the top message anymore, but the problem was broken browser and amusing 'blink' vs ' blink' confusion as detailed deeper in the thread. Also in chrome it doesn't appear to animate, removing the annoyance entirely.]

Interesting. I asked a few coworkers if it was just me and they confirmed it. The actual favicon doesn't blink for you? http://www.litfuel.net/favicon.ico

It reports itself as a 6 frame gif for me. Maybe your browser is just more sane than mine (Firefox 3.x) and refuses to honor animated favicons?

I figured I was getting rightly downvoted because I wasn't saying anything about NLTK.
