Where can I find free or cheap stock ticker software for mac?

I know this has been asked a few times, but I still can’t find an answer. I just need a basic stock ticker app that I can slap on my desktop during the day, but it needs to work for mac. I have an E*TRADE account but I don’t think they offer, however please correct my if they do. I hear sink or swim offers great free software but it requires signing up and I really want to avoid that.

Thanks!
