Last year I was invited to a Cookiepocalypse "End of the World" cookie party, the icon my friends had used on the invitation was the Mayan calendar with a bite taken out of it.
I immediately thought that it would be awesome to etch the calendar onto some ginger snaps for the party.
But I realized that, shrunk to the size of a cookie, all of the details of the calendar would be lost.
So instead I looked online for some vector versions of the Mayan Calendar or Aztec art to etch onto the cookies instead.
Since I figured that the whole calendar wouldn't fit on the cookie and be legible, I did a search for something that might work better, but still be recognizable as Mayan related art. The above image is what I settled on, since it was round and not too detailed.
