describe the most complex language that you have....does it use a text system or alphabet of its own and have you created it?

As the title says. I have been fiddling about with different websites and I have found one that allows you to create a font or alphabet of your own. It got me wondering if any of you guys have some cool or complex linguistic developments that your proud of.

My first dabble has led me to Anjanudic, it has a scriptoral system that looks akin to Arabic in parts but its not the same. It has the regular 26 letters but three of those are borrowed and are modern developments to translate works that use those letters for an Anjanudic audience. (x,y,k)

History wise, it was developed by a sub group of the broader Sarahawvi Ethno-Linguistic grouping and is related to other Sarahawvi scripts but this is the most widely used and has transcended the barrier of Anjanu Speakers and is used in other languages. Its usable with and without vowels but usage of vowels has grown, so it is in the transition from an abjad to an alphabet.

Its Fontstruct.com if anyone is interested.
