A puppet-animation based (loosely) on the Sumerian Epic of Gilgamesh, and made entirely with open-source software, except for a short animated section at the end which was made with Flash MX.
In this episode, Gilgamesh incautiously boasts that he can beat anybody in a fight - even his patroness, the Goddess Aruru. When Aruru herself hears of his boast, she decides to send a new hero to challenge him. Episode 1 of 10.
