I haven't seen anything quite like this anywhere else, but I think this is the closest forum to post it in. All these translation challenges, but how about a composition challenge? I've suggested this on the blog I keep (sometimes better than others), here:

I did not include IPA in my work, there, but I can update the post now to fix that.
My goal is to help all of us practice and develop our conlangs!
