Hoopism.com awhile back. The organizers on the site do a great job of turning NBA history and player statistics into creative illustrations. I enjoyed browsing through the complete history of NBA Championship rings in the illustration above. Click on the image to zoom in if you want the full view. A timely illustration considering Mark Cuban's idea to make his Dallas Mavericks championship bracelets instead of rings this year.
My favorite illustration on the site is NBA Slam Dunk Contest Poster. Want to know who competed in every slam dunk contest? This poster has you covered.
