There's a mobile phone mast inside the Arena Gallery. I don't suppose its a real one, its one of several works relating to mobile phones. I went to the opening last night but I need to go back to have a proper look at some of the items. There's photographs and videos taken with phones and a CD of remixes of ring tones as well as a computer displaying downloadable 'wallpapers' amongst other things.
Good to see a report made it onto the BBC website even if its only because of its novelty value.
