Skull-A-Day is an ongoing online art project/blog created by artist Noah Scalin. For its first year the site consisted of daily skull art creations made by Noah himself. After he finished his project, he (and a few co-editors) has continued to post daily images of skulls created by fans/co-editors to the site. The images you see above are from his first skull series 365.
