Lighting the diyas…
A free 3D Diwali night you can play in your browser. Walk through an old mohalla down to the river ghat, light 108 diyas, burst crackers with zero smoke and send a lantern into a sky that everyone playing shares.
Drone and laser shows go up over the river every few minutes, and lighting all 108 diyas starts the finale. No download, no login, and it works on most phones.
