A New 4th Plinth Artwork

A new artwork arrived on the fourth plint in Trafalgar Square this week - ‘Powerless Structures Fig. 101', replacing the Ship in a Bottle which was there previously - you may have seen my previous postings on the various offerings on trhe fourth plinth elsewhere in this blog.

Some good early spring sunlight and a vivid blue sky assisted my humble photographic efforts here and my polarising filter - which can at times be an almost permanent addition on my lens - was unnecessary on this occasion.  Whilst I don't always like aircraft vapour in my images, in the case of the 4th image above, perhaps they add something ?

Perhaps I'm missing something here, but what does the title of the artwork mean ?
