Whilst on my London Eye experience I noticed this strange purple cow which I thought was a temporary children’s play area. When I got home and researched udderbelly.co.uk I realised that it was a temporary theatre! :

Underbelly is a UK based live entertainment company. We run Underbelly at the Edinburgh Festival Fringe – one of the largest venue operations at the largest arts festival in the world – and Udderbelly Festival and London Wonderground at Southbank Centre in London. Our iconic upside-down purple cow venue – Udderbelly – is an annual fixture on both the London and Edinburgh skylines and 2012 was the inaugural year for our new London festival of circus and cabaret, London Wonderground.
