We have had a contest theme called ^What is it?^ a number of times in the past . Always fun and interesting, it also is interactive, leading Caedes members to not only choose the best overall image but also attempt to be the person who figures out the identity of the image (members would make guesses in their comments but the artist would only provide the answer after the contest concludes). It can be a unique angle on the object, a macro of it, or something few people have seen. Just a thought.
If you've ever wanted to make a difference but found it hard to believe that one person could... check out the Kiva Team Caedes discussion thread and discover that anything is possible.
"In photography symmetry appears when parts of your composition mirror other parts. It is created when two halves of your scene look the same and balance each other out." [https://www.theschoolofphotography.com/tutorials/symmetry-in-photography]
