Tumblr post consisting of drawings of two girls communicating with an angel, that only speaks through mathematical diagrams.

Pretty much exactly what the title says. I discovered the post last year, and it was quite obscure. I can't remember when it was posted, but the original poster's account was somewhat active.

I remember seeing it and thinking it was really profound, and I knew that if I didn't save it somewhere, I wouldn't be able to find it again. I had it reblogged but unfortunately my old tumblr account got terminated.

I believe it's mostly black and white, in a similar style to wojacks, except the girls look more like animé characters. They have a genuine conversation with the being, as if they understand it, while we (the reader) only see increasingly complex mathematical diagrams that aren’t in a speech bubble. I believe some were engineering related as-well.

That is honestly the best way I can describe it. I hope it gets found.
