i dont think theres a problem with graffiti being calligraphical...because in a sense thats wat graffiti is; its a form of street calligraphy. i would tyhink understanding calligraphy in the traditional sense would be quite beneficial to a beginner, because he will in a sense get a feel for letter structure and work his/her way up from taht. in case of nato...those are good ones...and i gotta give u a heads up..theres a nato in ny.....im just mentioning it...doesnt mean im saying change ur name.
