With just a few days until London's biggest-ever photo opportunity, it's becoming near impossible to excite, surprise or shock with a stunt. But if you want to create a stir, who better to help than Elizabeth Streb?
The boldness of this piece puts it ahead of the other performance art and antics adorning the South Bank on a daily basis. The surprise element added to the charm - lengthy build-up would have undermined the sense of wonder.
It's by-the-by whether it says 'Olympics'. One can assume that anything big happening at this time so close to a London landmark must be linked to the big 'O'. That's why London 2012 is so thrilling - it's about far more than just sport. Streb proves anything is possible this summer.
One might argue that the PR is the by-product of the performance art. Either way, it certainly secured enviable column inches.
