Did a quick search and didn't see this mentioned, so thought it should get a plug.
One day a year, the world stops to remember that joy we had when we first picked up a pencil and created our first piece of art - that's what Drawing Day is all about. The goal for Drawing Day is simple - to create enough drawings to make some noise worldwide for the sake of art. 2008 is the first year of this initiative. Our goal is definitely a long-shot, but we're aiming for 1 million drawings worldwide. We have no precise measure to know if we reach this goal. If we come close we will all definitely know. Even if we reach 10% of our goal in the first year of this initiative, it will be a great achievement but we will continue aiming for the magic million.
