Tate Liverpool, one of the Tate art galleries scattered around the UK (the two main galleries are in London, another is in St Ives) has opened an experimental online exhibition tour for iPhone and iPod Touch owners, which it says is the first of its kind in the country.
From now until the end of August, visitors to the Gustav Klimt exhibition will be able to browse the free guide content to their iPhones over the gallery's wifi network, or download it beforehand as a podcast. Spare iPod touches with the content pre-loaded will be available for hire for just $6 (£3).
According to an article about the experiment in Design Week magazine, the guide has been very popular and upped average visit times from 45 minutes to three hours.
If you want to try the tour for yourself without making the trip to Liverpool, you can enjoy it in full on the web.
