Experimentation seems to show that Firefox can play videos from here if you load them from my home machine, at https://home.vin-dit.org. That is a complete replica of this site.

Borasisi, the sun, held Pabu, the moon, in his arms, and hoped that Pabu would bear him a fiery child.

But poor Pabu gave birth to children that were cold, that did not burn; and Borasisi threw them away in disgust. These were the planets, who circled their terrible father at a safe distance.

Then poor Pabu herself was cast away, and she went to live with her favorite child, which was Earth. Earth was Pabu's favorite because it had people on it; and the people looked up at her and loved her and sympathized.
