The hajis love that crap. It looks exactly as you say it does.
Because the koran forbids representational art, the itsy bitsy tiles are arranged to make geometric shapes. So they end up looking quite “institutional”. It IS possible to make glorious art with mosaics, and it is a very ancient and venerable art indeed. There are some marvelous examples in Israel from the Roman Period. So it isn’t the medium that is a problem, it’s the MESSAGE. Wherever the human creative spirit is stifled and regulated, the result, though maybe technically excellent, is not “art”. It becomes merely “decoration”.
Just my humble opinion, of course!
