c6.org was an international media art and street art collective centred in London active from 1997 to 2010.[1]
The group combined graffiti, new media art and performance art with political commentary throughout the 90s.[2] [3]
The founder of the group Leon Sessix also makes street art and stencil graffiti under the name Dotmasters.[4]
The name originated from a roundtable discussion, Tudor Watson arrived late to the meeting, they were deciding on a name and there were six people present, so he said, how about 'See Six', which became 'c6'.
