The picture you see beneath is one of the treasures send by one of the Kimbooktu readers. I love it when you mail me interesting articles and products! The look of the building is absolutely brilliant. The designer and/or architect did a great job.
I was a bit surprised when I read what the purpose was. Take a look at the picture and have a guess. I will state the answer in the comments of the post.
Thanks to Marlise for sending me the link to this Flickr page with the photo on it.
