I joined this last year and love visiting the site to see all the new additions. Great concept, nice execution, wonderful purpose- for charity. It's the world's largest art project. You join, get your own little niche to decorate and then it's added to the big picture.


From the site:

The One Million Masterpiece is a global arts project. As a community we are creating a piece of artwork that will provide a unique snapshot of modern society through the eyes of one million people scattered across the world. To do this we are asking artists and non-artists alike to complete one small square of a giant digital canvas. The project is supported by the largest online arts communities, is an official world record holder and aims to raise $5 million for charitable causes.
