It makes me happy to hear about your start in commuting! Good job.
When I commuted, I just propped my bike against the wall next to my desk. It got lots of comments and inquiries (all favorable). Express messengers especially were interested (young guys, some of them kinda cyclicts or wannabe cyclists).
It also helped boost my own morale to be able to glance at my bike every time I got up from my desk, or returned to it, or just before I fell asleep at it...
