One of the most amazing things about Islamic art is how unstymied that average Muslim artist was by a religious prohibition. Beautiful caligraphy and abstract onyx and jacinth mosaics. But at a certain point, the prohibition lapsed enough that artists were able to begin composing drawings of animal and people out of calligraphy.
BibliOdyssey (a blog we woefully underlink, but is a daily read) has a beautiful gallery of examples. Ingenious: it really beats the shit out of the elephant I can make out of 'John'.
