Hmm, I see. Do you know if the calligraphy itself could be executed/interpreted? The idea of a visual representation of a program being art but also executable appeals to me.
A friend of the author of QLB here, and I brought up the idea of a visual interpreter to parse the square kufic calligraphy. My understanding (limited as it is by my almost complete ignorance of Arabic) is that certain stackings of adjacent words would be ambiguous to the parser.
