Modern experimentation

Modern graffiti art often incorporates additional arts and technologies. For example, Graffiti Research Lab has encouraged the use of projected images and magnetic light-emitting diodes (throwies) as new media for graffitists. Yarnbombing is another recent form of graffiti. Yarnbombers occasionally target previous graffiti for modification, which had been avoided among the majority of graffitists.
