Nothing says Christmas like Cthulhu!

The folks over at Red Wasp have designed a great app for the holiday season — the Cthulhu Christmas Calendar. Starting December 1, you can have adorably illustrated renderings of H.P. Lovecraft’s terrifying creations help you countdown the 25 days til Christmas on your smartphone or iPad.

This unique digital advent calendar contains an original illustration for each day that combines classic Christmas imagery like mistletoe with figures from H.P. Lovecraft’s Cthulhu Mythos, like Shoggoth mailing a letter to Santa, who, as we know, will find out if he’s been naughty or nice.

There’s also a multiple-choice question to answer each day, and you can post your results to Facebook. At the end of the 25 days, you’ll get your final score.

For only $.99, you can download the app for your iPhone or iPod Touch or for your Android phone; for $1.99 you can get it for the iPad.

The Great Old Ones will be rocking around the Christmas tree, as the Cthulhu Christmas Calendar is all the rage at R’lyeh, so make sure you get in on the action by grabbing this app for yourself!

Red Wasp Design has more in store for Cthulhu fans with their upcoming 3D turn-based strategy/role-playing mobile game, Call of Cthulhu: The Wasted Land.
