I have mixed reactions about the bytesize player. It's great the first time, but gets old after awhile. I thing turning the default to off is a good idea, but if someone new comes to the site, they might not even reconize it since there is no sound to alert them that it's there.

Well, maybe it's your choice of audio. Although the Endless Handbag Loop is a great track, it's a bit loud and quite sudden. Perhaps if you were to change the audio to something a bit more soothing, then people won't be frightened off. And give it a while before any animations play, let them explore the front page first, give them, say, 30 seconds or so?
