Read more about James, or follow his blog, Facebook, or Twitter accounts, at his main site:


There you can also find out about his involvement with the Enigma project, bringing the famous code machine to classrooms in the UK and internationally:

Running the Numbers


In Running the Numbers: An American Self-Portrait (2006-2009), Chris Jordan documents selected statistics about the United States in visual format.

For instance, click on what looks like Seurat's masterpiece of pointilism, Sunday Afternoon on the Island of La Grande Jatte, to reveal that Jordan has reproduced that painting out of aluminum cans--106,000 of them, the number used every thirty seconds in the United States. Similarly, zoom in on an image of tree trunks by clicking it, and see that Jordan made it out of 1.14 million brown paper supermarket bags--the number used in the US every hour.
