The current exhibition at Manchester City Art Gallery (as part of AND festival) is Recorder by artist Rafael Lozano-Hemmer. Most interesting of all his art pieces is 33 Questions Per Minute. As his website states:

“33 Questions Per Minute consists of a computer program which uses grammatical rules to combine words from a dictionary and generate 55 billion unique, fortuitous questions. The automated questions are presented at a rate of 33 per minute –the threshold of legibility– on 21 tiny LCD screens encrusted on the support columns of the exhibition hall or mounted on a wall. The system will take over 3,000 years to ask all possible questions.”
