Earth Architecture & Morocco Inspiration

I have been doing research on building techniques in Africa for a school project where we are creating a hypothetical resort in Morocco for a construction class. I was excited to stumble on this interesting-looking book called Earth Architecture that is scheduled to come out this fall. It focuses on homes built with earth. This book by Ronald Rael, makes the claim that "one half of the world's population, approximately 3 billion people on six continents, lives or works in building constructed of earth." The image below is of the Tebogo Home.Here's a close-up of the technique used.Here's an image of Moroccan earthen tiles that are just about to get glazed with colors.(image from the St Tropez Boutique of SF)

Here's an image of some inspiration found on Flickr of how Morocco takes the earthen architecture to a new colorful level.
