They describe the project thusly:
"You know all those naff advent calendars you get, where it’s always the same run-of-the-mill images… robins, candles, stars? Not particularly inspiring! Well Thunder Chunky has a remedy for your advent blues. We’ve roped in a selection of the best artists and illustrators around to create some xmas messages, especially for you!
We’ll reveal a new piece of work every day throughout December, so make sure you check back daily."
