We're starting to get into Minecraft territory here.
Someone just used the crafting tools in Fallout 4 to create speakers which then play the Fallout 4 soundtrack. I have no idea how people do these magical things. They should all be burned at the stake for witchery as far as I'm concerned.
Apparently it took creator Link Linky roughly 5 hours to create this thing.
It ends with an explosion. So there's that.
