"1945-1998" Nuclear Testing Timeline


Japanese artist Isao Hashimoto's multimedia piece, entitled "1945-1998," represents the 2053 nuclear test explosions conducted by eight countries across the globe. Hashimoto says, "This piece of work is a bird's eye view of the history by scaling down a month length of time into one second. No letter is used for equal messaging to all viewers without language barrier. The blinking light, sound and the numbers on the world map show when, where and how many experiments each country have conducted. I created this work for the means of an interface to the people who are yet to know of the extremely grave, but present problem of the world."
