Graffiti characters are something seen more-so in urban areas. While graffiti can be a form of art, it can also be considered a marking of territory by a gang or group of ruffians. Characters are typically completely unique to each group and are distinguishable by others. For example, a typical cross "T" would never be drawn as such. Instead, it may be bubble letter style with a downward spiral
. or jagged edge. There are many variations to make each character unique.
