Google recently hosted a company competition for its staff to spiff up their shared workspaces. This is the winning solution, which incorporates chalkboard paint, greenery and Android accessories.
A long box planter filled with succulents makes for a great divider, and the charcoal and Android green colour scheme adds a nice vibe. You could copy a few of these ideas for your own workspace (if, for example, you had a desk surface you wouldn't mind covering in chalkboard paint). More pics and details can be found in the Apartment Therapy link below.
