IBM has decided to take on carbon. Carbon is apparently the enemy of all green geeks... which is why you should buy an IBM (apparently). I'm not sure I follow all the logic, but none the less, I'm enjoying their anti-carbon videos. They include a Moose inspired green vandalist. The 'green' street art is created by cleaning the walls of tunnels, roofs and the underground, to show green messages such as, unplug, ride bikes, or stop wasting money.
