Escalator

I was thinking "abstract" for today's challenge as I walked through Westfield in the city this morning and I saw these escalators wth fresh eyes.  I added an extra to show the diverse range of images this spot had to offer.
There is an interesting aside to this shoot.  A gentleman showed interest in my activity which started a photography conversation.  He reported having been taught by Max Dupain.  
Thank you Ingeborg for hosting today's challenge with a travel theme.
