KPI Monitoring in Real Life

Physical build status indicators are quite the rage and have included examples ranging
from Ambiant Orbs to Lava Lamps.

What about taking it to the next level? In my budget next year, I have money for a
42″ plasma screen to mount on the wall in our development area. The plan is to have
this screen show real time monitors of build status on various projects, defect counts,
and other KPI meters.

We want alarms to sound, we want to hear an audible sigh of relief when the build
is fixed, etc.

What software do you know of that makes a good KPI monitoring dashboard for a group
development room?
