note apart, the drawing is INSANE
It shows how to ponder an Orb, which is about visualising the mathematics of a sphere. Specifically its internal geometry, I believe.
You can use that to program a virtual world stored inside your Orb using abstractions from your own mind (like a lucid dream universe).
It would look something like: https://www.mathsisfun.com/geometry/circle-theorems.html
Circles have infinite data points internally, just like spheres.
Somone made a 3D version of it in Blender (and I’m kinda mad it’s not an animation that looks around in the room or something):

Amazing stuff.
Classic art converted into modern memes is my favorite weird niche of the internet
ponder your own orb.

(just a warning tho, the game is only half done and likely will never be finished, but it’s the best there is at what it does and all the pretenders suck really bad)
Fantastic
