Wednesday 11 April 2012: Big white inflatable thing
This dirty great white inflatable object appeared on the Mound this afternoon.
From the little research I did, I think this is to house the 'Bang Goes the Theory Interactive Arena', starting 13th April. I waited until the staff turned round to see what this nosey parker was up to, which they obliged before moving on to other inflatable-related activities. Also liked the spot of colour provided by the chap in the middle.
