From the foundry
This is not a Nastaliq font but a SiahMashq font — 'black practice', what happens when you practise with the Nastaliq Persian calligraphic script. It reproduces the black-practice effect simply by typing: a random structure of Nastaliq letters delivered as an ordinary TTF/OTF font, with a colour version, RanginMashq, in which the letters' colours behave like overlapping Photoshop layers.
