I would like to show you a web site I found where you can have your Farsi text displayed in beautiful Nasta’aleegh calligraphy.
You don’t need a Farsi operating system or extra software for generating beautiful writing. You can become “khosh-khatt” after all these years! You can type in the box provided for your text, or you can copy/paste your text from other sources.
Here’s the website’s address: http://nastaliqonline.com/
