Postgrad and David McCandless are putting on a Data Visualization contest in which I will be one of the judges. David posted on twitter he had some great data about black students at Oxford and other UK Universities but he didn't have the time to make it visually appealing. So Postgrad teamed up with him to offer an iPad 2 as well as a signed copy of "Information is Beautiful" by David to the winning graphic or visual.
You can see Postgrads post for the full details. If you have skills and are looking to show them off I would recommend entering the contest just for the exposure let a lone the prizes.
