One of my viewers requested fire that rains down from the sky with a message in chat - so I came up with this ritual of fire where you place one standing log of jungle wood surrounded by hay bales and throw on a torch to summon a rain of fire from the sky.

Not the most polished of concepts, perhaps, but I thought it was pretty cool anyway. You can get it by downloading the world or the schematic, or you can use the "one command" form - just paste the command into a command block, place a button on it and press the button. When you have the machine in your world, press the button on one of the command blocks.

If you want a full explanation of how it works - take a look at the video.
