We run a full AppView + PDS + Relay for ~$1,772/mo. PDS is cheap (~$0.03/user/mo, 4 vCPUs, 32GB RAM). AppView is the expensive part; indexes the entire network (16TB DB), not just your users. Storage scales linearly with network activity. PDS scales linearly with your account count.

I have a mesh topology library that takes pluggable algebras. Here’s sphere inversion by creating an icosphere using PGA3D, then inverting it through another sphere using CGA3D. The effect is a bit like Escher’s conformal map visualizations, but on a triangle mesh.
