Video journalist: Christian Parkinson made this film for the BBC about James Wannerton and his work.
Londoner James Wannerton can taste and smell words, images and sounds because he has synaesthesia, a condition which links senses that are usually separate.
Over the years he has built up a taste and or smell for every station on the London Underground, his very own Tube map. Some tastes are enjoyable; the English breakfast taste of sausage and eggs at Tottenham Court Road, others unpleasant like the choking smell and taste of hairspray at Bond Street. Interestingly when asked if he would want to be free of these sensations, James said he would not.
He hopes his map will help promote understanding about the condition.
