Question: It's time to propose the topics for our Challenge Week!

Some notes:

1. Propose one topic per answer (make it CW by checking the checkbox under your answer);

Write them like  

`## Topic <br><br>  

"description"`.
2. No maximum of proposals, but don't just propose tons of stuff. Propose things that could stimulate questions and answers.
3. Vote other proposals **up** if you like them, and **down** if you don't.
4. Include a short description or notes, otherwise the system won't let you post your answer.

For each Challenge Week, we'll take the most voted proposal (excluding the already asked ones), so keep proposing! Don't wait for others to propose!
