We can see it now: the agonized grimaces of the roasting chestnuts, the city sidewalks dressed in Santa suits, the cliquish reindeer gathered around the Monopoly board. Take a Christmas carol, Hanukkah tune, Kwanzaa ditty, Diwali chant, Equinox dirge, etc. and render its lyrics in graphic form. We've done this before with song lyrics, and movie titles, and book titles, and TV show titles, and famous quotations, so take a look at those Derbies if you need a sense of how to approach the subject. Call your entry "Inspired By (Song Title Here)". And you'll probably do better with the voters if that song title isn't "Grandma Got Run Over By A Reindeer".
