Recently, I was asked to build some kind of room divider for a house. I figured the best plan would be to build a suite of top hung sliding doors. So that's just what I did. There are four separate tracks in the top jamb, and each door is able to slide past it's neighbour. I used 1/4" tempered glass, in a pattern called "rain". The doors are Douglas Fir, and are still quite blonde. Over the next few months, they'll oxidize to a warm amber hue.
