I've seen this guy at work a lot now. A lot of the time I don't have my camera (at least not the good one) or he scoots off before I can get him, or I just don't bother trying because I know he'll be around again, but most of the time because I am always late for work. But I got him today (with my Sony point and shoot, so it's not that great). He is always singing when I arrive at and leave work at the southwest corner of the tower. He's my little buddy!
