Most of us cyber geeks love a good shot of graffiti art, be the murals absurd and fun or masterworks by Banksy, but the reality is that most of this stuff is ephemeral at best, gets covered over by paint crews pretty quickly (at great cost to Joe Taxpayer) so they live on primarily through photographs. If that's the case, why not create graffiti art that only exists in photographs?
