DailyScienceFiction.com bought the right to show this tessellation illustration at the top of each story that appears on their website during the entire month of October, 2012. This tessellation appeared together with those stories on their site, and in print, in perpetuity. 'Way cool!
This tessellation also won the most prestigious online tessellation contest in the year it was drawn. It's one of 3 pieces that I've made & won that contest with.
