I have to disagree with you on the point that designing an Arabic font is an easy feat, unfortunately it isn't. Maybe for the run-of-the-mill, cookie-cutter typeface, this could be true but if you'd like to import a certain style to the Arabic script, you'd face the usual constraints and limitations of the Arabic letters that they are not as malleable and flexible as their Latin counterparts esp. if you're aiming for 100% style consistency and uniformity across the set.
This is a fixed monospaced Arabic font [0] and I'm pretty sure it took the author a whole lot of time and effort to pull this great work off.
