![Bad Apple, but rendered with hyperbolic planes
Our take on the famous Internet meme! If something can display something, it will display Bad Apple. If it cant, people will make it display Bad Apple. LiterallySomeOne, [2]
By the Riemann Mapping Theorem, every simple-connected shape can be conformally mapped to a hyperbolic plane, and thus be used as a model* of hyperbolic geometry.

* rather a projection than a model... but people call them models, so lets call these anime-girl models
