Vinux is an Ubuntu-derived distribution optimised for the needs of blind and partially sighted users.
Being based on Ubuntu, both the Live CD and Live DVD versions come with the same boot screen the one used on the main Ubuntu OS, designed to allow the user to choose a language from the get-go.
Vinux comes with an accessible suite of software and has an excellent mailing list support group.
When booting the live Vinux image, the users are greeted by the Orca screen reader that enables them to navigate the graphical Unity desktop using keyboard commands.
In conclusion, Vinux is a really great project that will try to help blind and visually impaired users to manage their way through a quite perfect clone of the Ubuntu Linux operating system.
