What it did on its own 👇

⛈️ Simulated the storm on a 30.5M-cell grid: rising air, rain, ice and electric charge, with 63 flashes logged
🌩️ Grew the bolt with a dielectric breakdown sim: 16 m grid, 53,505 cells, about -110 MV at the root
👁️ Rode the camera on the tip for all 60 steps of the leader
🔥 Burned the scar with the same kind of physics into a prairie of 2.4M grass blades
🎧 Synthesised every sound: the hum climbs with each step, then 130 ms of dead silence before the crack
🐛 Caught the bolt stopping 752 m above the ground and resumed the sim instead of restarting it
🚨 Scanned every frame, found a full-screen strobe at 4 to 6 Hz and fixed it before I ever saw it
