Modular Arts Panels (http://www.modulararts.com/) are textured wall panels that are describes as "cast rock". They can be painted and are more durable than drywall AND They look amazing installed.
I have used Modular arts before; most recently in Vancouver's Jameson House amenity areas. I used the Stream design installed horizontally and grazed it with light. I think it will add some amazing texture and interest to the room. I will have to post pics when it gets installed.
What I just came across today in my Interior Design Magazine is a new design that I am in love with. It's called Tucker and it looks just like a tufted fabric wall. I can't wait to use this in a project!! It looks cozy and soft but it could be used in any commercial application that fabric can not.
