Nina Paley’s “Sita Sings the Blues” is becoming a huge critical success, and may even succeed financially, which is unusual for any independent film, but virtually unprecedented for free culture films (“Sita” was released under the CC By-SA). There’s only one sad thing about this for free software fans, and that’s that “Sita” was made using proprietary software, and the “source code” is in a proprietary format: Adobe Flash’s “FLA” format, to be precise. Paley has posted these files on the Internet Archive, but she doesn’t know how to translate them into any free software friendly format (and neither do I). Can you help?
