"The Morevna Project aims to create an animated film in
a modern anime-style retelling a very old Russian folktale known as
"Marya Morevna". It's a free culture production project pushing the
envelope in several ways — entirely using free software tools
and releasing under the free Creative Commons Attribution license.
The project is purely community-based, without any foundation
funding, so they can probably use your help. Joining could be a
terrific learning opportunity, whether your interest is in
literature, music, animation, or software development. Marya
Morevna: The Fairy Tale
"It's probably essential to give an idea of what the original
story is about, though it may seem a bit bizarre (this was
certainly my first encounter with the story).
"The protagonist, a prince named Ivan, has three sisters to
whom, on his parents dying wish, he grants permission to marry
three men who are apparently some sort of bird spirits in reality.
He himself runs off with the powerful queen Marya Morevna (it's
notable that she's a "queen", not a "princess" in the story)."
