I had a dream this morning at some point that I read an article about Batman only eating round food, only things that either came in ball form or could be shaped into it. There was, accompanying the article, a loose painting illustrating this idea, with Batman holding a plate of what I knew were spherical pieces of vegetable (carrots, broccoli, and potatoes).
I think there may have been a table in there too, but I couldn't get it to work well. Plus it was mostly in shadow.
