Novelist Teju Cole is trying out a new Twitter experiment this morning, letting loose a string of more than a dozen tweets that tell the story of a public heart attack. The tweets come from different accounts, only brought together on Coles feed. One of the accounts, @MisterSimian, has confirmed to The Verge that the tweets were solicited by Cole in advance, suggesting that the work was written as conventional prose. Other accounts include comedian Rob Delaney, two poets and several other writers.
