Show HN: A minimal TS library that generates prompt injection attacks (prompt-injector.blueprintlab.io)

I built a simple simulation of a Dyson Sphere using C++ and OpenGL. It renders ~20,000 satellites orbiting a star, with adjustable parameters like satellite size, density, and distribution.

The goal was to explore graphics programming and visualize how such a megastructure might look. It’s still work in progress, but functional enough to share.
