The World's Deepest Bin

I did think that these 'viral' adverts (the piano stairs one is doing exceptionally well on Facebook - I've seen it several times today!) were from a car company - they were so smooth and polished - and yes, there we are Volkswagen, doing some social action work - and having fun whilst at it. I heartily approve of this!
