Heard of the sketchbook project? If not, you should check it out. The Sketchbook Project is a national art project based out of Brooklyn. Essentially, it will be a huge collection of sketchbooks gathered from thousands of artists that are based on a variety of preselected themes. Anyone can participate.
The sketchbooks will tour the states being showcased in museums across the nation. After the tour, the project will become a permanent exhibit at the Brooklyn Art Library. Pretty cool, eh? But there's something cooler. The sketchbooks can be checked out like library books. Each book comes with a barcode. Every time your barcode is scanned, you'll receive a notification. So, you can track the popularity of your book. Neat.
