Challenge completes when Winter Bash Starts - Happy Winter Bash Warmup!

Gentle reminders that some may find helpful:

1. do not fall victim to the 'get-it-done-fast' trap. There is no prize for the early entries, and there's almost 10 days to get it done. If that's not enough time, there's no reason to even post your question before then either.
2. there are no prizes at all... just good questions and good answers. The prize is the satisfaction, and reputation, that you earn.
3. the idea is to extend yourself in ways that you would not normally do. The challenge is just something a little inspiring, if your interest lies in only a part of it, then implement what inspires you. The advantage of the challenge here is that it gives you something in common with other people too. That makes it more fun (if that's your thing).
4. Come and chat about things in the 2nd monitor. These are called community challenges for a reason, they help form a community. Come and join another side of the Code Review community in chat.

WinterBash will be starting in 2 weeks. Let's put up a code-challenge to complete before that. Like previous challenges, this meta post is here to poll for a good challenge idea. Here's how this round will work:

1. Post an answer to this question with your challenge
2. Vote for those answers which interest you
3. At the end-of-day on Thursday, 4th December, the most-voted post will become the week challenge.

Once the challenge topic is decided, you can post questions on the main-site related to the challenge. The idea is to run the challenge all the way through to the start of WinterBash, which starts on the 15th Dec (I have been told).
