Sudhindra Rao from ThoughtWorks has released a Build Radiator (Big Visible thing) for all the CruiseControls that support CCTray.
I installed it tonight. Needed to install the rack and activerecord gems. It would be nice to see it wrap around if you have more than a few projects. Most teams would probably do fine with this on a big display, I suspect.
This is pretty much what Michael and I did last year, except Sudhindra has made his nicely generic. Oh, and open source and available to the public. That helps a lot.
Nice work, Sudhindra.
