Any ideas for creative ways to involve Yelling Mule staff in social media campaigns?

We're a design / development company and sometimes things get very quiet here. Everyone is on a computer all day.

I've always seen the most engagement and interaction from posts involving people.

What I want is to do more social media campaigns or projects involving the staff at Yelling Mule - you know, to get them moving (in or around the office) or get the interacting!

I'd love to hear ideas on creative things we could do as an office or involving office members that could also benefit our social media efforts.

Any and all ideas are appreciated! :)
