Flash - "Britains Cleaner"

[advertquery]

Does anyone know the LAST piece of music on the recent flash advert "Britains Cleaner". It's a string piece that I have heard before. The advert it is viewable online:

brandrepublic.com/sectors/advertising/creative/advertisement/28136/

I'm sorry this isn't in the advert section, I am new to this website and there seems to be no way to get to the advert section from the navigation.

I knew the first 4, but have no idea what the last one was; I've never heard it before...sorry!

Your not the only one that would love to know the name of that piece of music - It's starting to really annoy me because no-one seems to know - I'm not really a classical fan but that piece of music is really good.

It is Perpetuum Mobile by The Penguin Cafe Orchestra

it isn't perpetuum mobile, it coulds be something by Steve Reich but I'm not sure about that.
