Anyone has attractive ideas for Booth Attractions? Something uncommon and eye catching?

The Company i work for will be participating in an International event in the US this year, and I am trying to find ideas for attracting the events attendees.
Pens, notepads, mousepads & such stuff are so common. Can anyone help me with uncommon and attractive ideas?

What ways could we attract clients to our booth at a home town event?

We are a local Mortgage company, I need ideas outside of the box. Not little pens, or key chains. Something that is different. Please share your ideas.Thanks
