Commentating without looking

Commentating a game of cricket is not something that most of us can manage.

Doing it without the use of your sight seems near impossible.

Dean du Plessis is the world's first - and only - visually impaired cricket commentator.

Based in Zimbabwe, he uses sounds generated by the bowlers' drag and batsmen's bat to comment on proceedings.
