My wife (who knows much more math than I do) is apparently dubious about this one. I feel that this merely validates the concept.
Octo𝜋
Octo𝜋 was apparently summoned during a particularly unfortunate seminar on pure mathematics; judging from surviving notes (before said notes devolved into the traditional inhuman, babbling screams) a professor was attempting to demonstrate what pi might look like in an eight spatial-dimension space, and… well. He apparently succeeded. He just wasn’t expecting Octo𝜋 to be hungry when it arrived.
