Just came across a pretty cool tool.

A ticker that constantly scrolls on your the top of your browser showing domain names for sale or at auction at sites including:

Sedo

Afternic

DNForum

Pool

NamePros

SitePoint

If you are interested on a domain you see scrolling, you can just click on it and it will take you the site, so you can place a bid.

The  ticker is free, works with Internet Explorer and Firefox,  and you can download yours at:
