For those of you that have art hanging on your bathroom walls, what does it look like?

I was sitting in the tub this evening and I got this harebrained idea to paint some things to hang up on my large, empty walls in the bathroom.
Problem is, I have no idea what I want as subject matter. I only know that I do not want flowers/anything floral. Which is not great, because I mostly paint flowers and portraits.

So basically I’m just looking for inspiration. Not necessarily suggestions, just lots of ideas that might spark something for me. What do you have on your bathroom walls?
