I love lettering and typography, so calligraphy being a form of that, I immediately take notice.
Arabic is such a unique beautifully written language. eL Seed (French-Tunisian) has created something called calligraffiti to describe his street art, which is a mix of calligraphic Arabic lettering with a geometric touch.
To me, it's outstanding.
