3Desmos
These two graphs are the result of me playing with 3D projections in desmos, which is a bit of a rite of passage in the desmos community. The first one was my first "big" project in desmos, and I didn't know anything about projective geometry when I made it, meaning that it's a bit of a mess. The second one is more stable and mathematically correct. I'm linking to both, but I vastly prefer the second graph.
