I'm selling 2 tickets to the Observer Ideas festival, Sunday 12th, at the Barbican. I admit I got them free but need to make some quick cash! *cheeky* 2 tickets are worth £150, but I'd be happy with £70.
'Observer Ideas is a one-day festival of talks, debates and performances with a variety of speakers including scientists, mathematicians, chefs, campaigners, musicians and environmentalists. With live music throughout the day and subjects ranging from technology to art, from science to food, and from big data to the economy this is a festival of the mind designed to inspire, challenge and maybe even provoke.'
