I'm not in the office today, but I did notice they are testing out the videoboard today. Probably just test patterns and such (I really can't see what's on there right now from the webcam, but it's getting tested :-)
Here's the image around the time of this post.
I will have more details when I am back in the office tomorrow... I should be able to put my own test content on the board by the end of the weekend... fingers crossed!
