Drown out your annoying neighbors (and get some writing done)

I just found out about this free Web application that lets you blast white noise through your computer or iPhone.

By the way, if you're a Pacific Crest Trail hiker, you're out there hiking with an iPhone, and you want to drown out your chatty trail companions, you might want to think about this, too. Just put on those headphones and put the volume on full blast.
