Creative ways to add a wall

[Craig Baute - Creative Density Coworking]

We just expanded and I have a room that needs to be made into a meeting room with privacy.  The room has a traditional office drop down ceiling that is about 8 ft tall and it's about 14 ft long. I could build a standard wall, paint it and call it good but I would love to know if anyone has done something different that still served the purpose well.
