...It turns terminal contents into the background sky, so nearby text bends, stretches, magnifies, and disappears through the simulated gravitational lens. The shader can run in different size modes, including a Pomodoro-style timing mode, a Claude Code token mode, and a demo mode. In token mode, the black hole grows as Claude Code’s context window fills, creating a visual warning before compaction becomes necessary. The project uses a single fragment shader and live physics-inspired rendering rather than static overlays. It is useful for terminal customization, visual experimentation, and playful feedback during long AI coding sessions.
