Oulipo were/are a group of writers who would not write a novel or a poem without first imposing rules on themselves to constrain what they wrote.
There is no better Oulipo resource on the web than Derek Badman's list of novels written using Oulipo-like constraints.
Not the least pleasing of the novels listed was ‘Negativeland’ by Doug Nufer.
No sentence in Negativeland was expressed with a positive construction.
Nufer does not discount the possibility that the inspiration for this was the number of rejection letters he had received from publishers for his previous novels.
It was announced this week that Stefan Bruggeman’s ‘Show titles’ did not win the 2006 Becks Futures art prize.
