The Economist  has released a new toy for those interested in the Middle East. Following on from its remarkably prescient "shoe-throwers' index" , the magazine yesterday released a brand new version of the index  which allows you to fiddle with the inputs.
The previous index measured unrest by examining the length of time a ruler had been in power, how democratic the state was and how much corruption there was in society, among other factors. This time, the Economist has included adult literacy and the proportion of internet users in a country. Have a play and work out which despot will tumble next.
