Bedwyr Williams represents Wales at Venice Biennale

Conceptual artist Bedwyr Williams is representing Wales in the Venice Biennale, a major contemporary art exhibition that takes place once every two years, in June 2013.

BBC Wales arts correspondent Huw Thomas went to meet the Caernarfon, Gwynedd, based Williams to hear more about his work.

He is taking amateur astronomy as his theme although the exact detail of his new work is being kept under wraps.
