Street Art Graffiti Shadows

Techniques
Whereas traditional graffiti artists have primarily used free-hand aerosol paints to produce their works, "street art" encompasses many other media and techniques, including: LED art, mosaic tiling, murals, stencil art, sticker art, street installations, wheatpasting, woodblocking, video projection, and yarn bombing.
Traditional graffiti also has increasingly been adopted as a method for advertising; its trajectory has even in some cases led its artists to work on contract as graphic artists for corporations. Nevertheless, street art is a label often adopted by artists who wish to keep their work unaffiliated and strongly political. Street artists are those whose work is still largely done without official approval in public areas.
For these reasons street art is sometimes considered "post-graffiti" and sometimes even "neo-graffiti." Street art can be found around the world and street artists often travel to other countries foreign to them so they can spread their designs.
