This listens to 6 LAPD scanner feeds 24/7, transcribes them with Whisper, and tries to figure out where things are happening. When it finds a location it geocodes it and puts a dot on the map. You can click any dot to hear the original audio and read along with the transcript.
Search box understands stuff like "shots fired last 2 hours" or "pursuit yesterday." The transcription is pretty bad sometimes because scanner audio is rough, and the location extraction is wrong more often than I'd like. But when it works it's a cool way to see what's going on around LA.
The idea: you're fighting near black holes, and Schwarzschild time dilation is the core mechanic. Get close to a well and the universe outside speeds up relative to you. Enemies move faster, projectiles zip past, weapons cycle quicker. Pull back out and everything normalizes. Single and binary black hole configurations make things pretty chaotic.
Weapons and AI scale with local dilation, and there's procedural audio that shifts based on how deep you are in a gravity well. It's free, runs on Windows/macOS/Linux/web.
Built the whole thing solo: physics, AI, procedural audio, rendering, deployment. Happy to talk about any of the technical choices.
