Mario Lemieux was to Pittsburgh NHL hockey what Michael Jordan was to Chicago NBA basketball. In an interesting tribute, the Penguins worked with the Mario Lemieux Foundation to create a tribute - a mosaic commemorating his great career:
The cool part is that this mosaic is made up of 21,000 individual photos submitted by Lemieux fans. And it is online, in fully zoomable form. Give it a try - the zoom feature is fascinating, as are the photos.
Not something you see every day.
