Unlocking so we can have some discussion. Minim, I appreciate the effort to keep the challenge board tidy, but a good moderator has to treat people with courtesy first of all.
When the challenges forum was more active, this kind of post, challenging others to replicate an achievement rather than asking an open-ended question about what can be achieved, would have gone in the "Oh No! More Challenges" thread. But that hasn't been posted in since 2012. I am not sure it's a good idea to bump it or merge this into it. If more challenges like this crop up, then yes, we can restart a general challenges thread. For now, I think it's best to just let this be. Regardless of what we ultimately decide about where to collect the post, it's an interesting challenge, so there is no call for locking it.
