Centenary Poppies

100 years ago today, the First World War started and it would be no exaggeration to say that it changed the world. Tanks, machine guns, trenches, aerial combat... all firsts (?) and all on a global scale, with a commensurate number of deaths.
Of the many artistic responses this summer,  Paul Cummins's massive installation of ceramic poppies at the Tower of London is the most dramatic. Currently there are about 100,000 of them but it will number over 800,000 by Armistice Day, one for every British and Commonwealth soldier who died.
