Alternatives to Reference Desk Signs

I’m looking for ideas for labeling, designating, or somehow bringing attention to a reference service point in an information commons environment.  Although we do have a reference desk in our new Learning Commons, a sign for the reference desk was not part of the original plan.  There is at least some feeling that signs are too formal for this type of collaborative space.  On the other hand, there is some confusion for those seeking help, especially if they don’t know that in-person reference service is offered in the Learning Commons.


I’m interested in any ideas as to how to draw attention to the reference service point.  This could be either effective ways to use signage without turning students off.  Or other ideas to help clarify the existence of the reference service point without signs.
