Street Graffiti

Another form is the "throw-up", also known as a "bombing" which is normally painted very quickly with two or three colors, sacrificing aesthetics for speed. Throw-ups can also be outlined on a surface with one color. A "piece" is a more elaborate representation of the artist's name, incorporating more stylized letters, usually incorporating a much larger range of colors. This of course is more time consuming and increases the likelihood of the artist getting caught. A "blockbuster" or "roller" is a large piece, almost always done in a block shaped style, done simply to cover a large area solidly with two contrasting colours, sometimes with the whole purpose of blocking other writers from painting on the same wall. These are usually accomplished with extended paint rollers and gallons of cheap exterior paint.
A more complex style is "wildstyle", a form of graffiti usually involving interlocking letters and connecting points. These pieces are often harder to read by non-graffiti artists as the letters merge into one another in an often undecipherable manner. Some artists also use stickers as a quick way to catch ups. While certain critics from within graffiti culture consider this lazy, stickers can be quite detailed in their own right, and are often used in conjunction with other materials. Sticker tags are commonly done on blank postage stickers, as these can be easily acquired with no cost on the writers part.
Many graffiti artists believe that doing complex pieces involves too great an investment of time to justify the practice. Doing a piece can take (depending on experience and size) 30 minutes to months on end, as was the case for Saber MSK while working on the worlds largest graffiti piece on the LA river. Another graffiti artist can go over a piece in a matter of minutes with a simple throw up. This was exemplified by the writer "CAP" in the documentary Style Wars, who, other writers complain, ruins pieces with his quick throw ups. This became known as "capping" and is often done when there is "beef", conflict between writers.
