Enrico Casarosa is the architect behind this very cool premise. On Sunday, March 6th, artists from all over the world will meet, wherever they are, and spend the day wandering through their city, documenting their day through drawings. People post their drawings to the site when the day is done to share with everyone. Now, artists generally take their books out to draw on their own, but this is an actual organized event that will happen simultaneously in several different countries. How Enrico got this to be an international event I have no idea, but it's probably the coolest thing ever. And a great way to make artist-friends in your area!
