Lightning Simulator vs Coze

This is for all the lightning lovers out there. Turn your room into a thunderstorm. Lightning plays immersive thunderstorm soundscapes and syncs the light to the thunder: the screen dims to black, then pulses and flashes with every rumble — and on the loudest strikes, fires the camera flash like real lightning. Set the storm's distance and the thunder trails the flash, just as it does in a real storm. Best experienced in a dark room, with the screen and camera flash exposed and the audio through speakers or headphones. Made to fall asleep to. A sleep timer gently fades the audio and light to black instead of cutting out, so it never jolts you awake.
