Thanks, that was the point of the walls, they've been everything from jungle ruins to an underground bunker to a medieval castle. Its pretty handy stuff that can be dressed up in multiple ways. Due to a lack of storage space I try and make all my terrain as flexible as possible and then have some handy boxes of set dressing to give it the right feel.
If you go through the pulp and www2 games on my blog you'll see this time and time again.
