    Skylight

    Skylight

    Project the aircraft passing overhead onto your ceiling in real time

    ...It decodes ADS-B signals from an RTL-SDR radio or can use a web API for testing without radio hardware.

    Ghostty Blackhole

    Ghostty Blackhole

    Ghostty Blackhole puts a real, ray-traced black hole

    Ghostty Blackhole is a Ghostty terminal shader that renders a ray-traced black hole directly inside the terminal window. 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. ...
