Thomas Heatherwick Studio's art installation/sculpture in the Wellcome Trust building. Taken during London Openhouse where they were very happy for us to take pictures.
And I saw another young lady my age or a bit younger/older with a MF folder. I have been outdone this time!
At first glance from the thumbnail I thought this was the view up into the fly gallery of a theatre, since I recall you involve yourself in theatre production work from time to time. My first impression was 'holy moley that is a lot of fly lines'.
