As I told somewhere else, a self-proclaimed artist whose only info I have about is that he was (hope he still is) Belgian(*), dropped by in these surroundings in the eighties, and fell in love with this wonderful semi-desertic scenery made of reddish earth and pink granite boulders (see Tafraout pics to have an idea of the colours). Those massive stones, sometimes rounded, sometimes in mushroom shapes, are scattered around as if a giant hand had thrown them at random. This guy had the bright idea of going there, in the middle of nowhere, to paint many of those boulders in various blue and red tones, and making some sign on them, following his artistic inspiration. We have arrived there thanks to a local guide who was trying to convince us to visit his family shop (Berber handicrafts and carpets) in Tafraout. He stepped onto our rented car and lead me driving thru a place only reacheable by goats and camels, a very dirty unpaved desert road with many forkings leading into nowhere. No signs, I would never be able to go there again... Our guide is the guy with a blue dress in the pics.
You may decide yourself wether or not the work may be considered a piece of art, I can certainly say the the trip was worth it, both for the human and (maybe even more) for Mother Nature's work of art you can admire, and also for the adventurous drive thru the desert...!!!

(*) If any of you has further infos on this artist, like his name and his works, please   because I am curious to know some more about him.
