that is a whole lot of fun, Wendy! love it!
Asymmetry is really just about things not being balanced. I think most of us tend to be pretty linear in our scrapping approach, with photos usually being square/rectangle, so it's just an idea to get a more free flowing page design. You could take a basic approach to the prompt by scrapping predominately on one side of the page...
or by scrapping on non-mirrored off kilter sides of the page:
the clustering on this page is asymmetrical and would work for this prompt:
or by allowing your "design" to be really organic and free flowing :
I hope that helps. I'm looking forward to seeing what everyone creates with this one!
