The artist Jane Kim has created some huge and amazing murals of monarch butterflies. See this photo of the side of a building in San Francisco. See the Migrating Mural section of her website for more murals, the featured work page for non-butterflies, and her Instagram page for more frequent postings. I think The Wall of Birds at The Cornell Lab of Ornithology is particularly great.
There’s also an absurdly awesome $295 shoe, if you’re into that kind of thing.
