Artist shares thoughts on possible Sudan break-up

Millions of people in southern Sudan are preparing to vote in a referendum on independence.

The ballot, which begins on Sunday, is likely to see the south break away from the more developed, Arabic-speaking north.

While much media attention has been focussed on the south, the question of a break-up has huge emotional resonance in the north following years of civil war.
