Might not interest all, maybe only The Fiend but... Graffiti Analysis is an extensive ongoing study into the motion of graffiti. Custom software designed for graffiti writers creates visualizations of the often unseen motion involved in the creation of a tag. Motion data is recorded, analyzed and archived in a free and open database, 000000book.com, where writers can share analytical representations of their hand styles!
graffitianalysis.com shows you how to and gives you the code etc...
