When I was around 11 years old I saw a TV programme about an extrodinary British boy just a year older than myself. His name is Stephen Wiltshire and he has not just a photographic memory, but the ability to then reproduce what he has seen on paper.
In May 2005 after a helicopter flight over Tokyo he drew a 10 meter long 360 degree panorama of the city over the following 8 days. Possibly the greatest feat of memory there has ever been.

I love Stephen’s work, we have a shared interest in architecture and classic vehicles. Several years ago I even bought a tiny sketch he had done of a New York taxi. It seems that taxis have become one of his favorite things to draw, but for me his most awe-inspiring pictures are his cityscapes of London and New York.

Next time I am in London I plan to visit his gallery, but until then I’ll continue to keep up to date with all his work at his website.
