Sony has not officially endorsed the various pieces of art, and claimed to be unaware of such a campaign. However, claims on the Internet are that Sony paid for the characters to be painted onto public and private property as an advertising campaign. The characters were all very well created, and all were somehow playing with Sony's PlayStation Portable (PSP) console.
Here is the source news article with some pictures of the defaced PSP art: http://www.secondaryscreening.net/static/archives/2005/11/index.html
