300 Mystery

You're all familiar with the 300 UCLA Medical Plaza building shown above. That's the one with the odd Roman numeral 4 on the clock written as IIII instead of IV. See http://uclafacultyassociation.blogspot.com/2012/01/discovery-of-new-roman-numeral-at-ucla.html

Today, workers were changing the sign. Donation? Someone wants a new sign? Who knows? Presumably, we'll know soon.
