> That thought would be interesting enough to chew over, but the researchers have gone one hypothesis further: that the fire was more than mere illumination and its flickerings acted to provide a primitive animation to the plaquettes’ carvings. I just checked, and LED lighting wasn't invented until much later than 15,000 years ago. So, whether they benefited from the primitive animation or not, I am confident they would have displayed their art by firelight anyway.
