Unconventional Reef Keeping Ideas??

[SeahorseKeeper]

So, I saw this thread https://www.reef2reef.com/forums/zoa-discussion-club-zoa/153792-my-zoa-paly-system.html and I am wondering what other unconventional ideas are out there?

I'm thinking of redoing some things in my tanks and I am looking for some inspiration. Please share your ideas!
