I wish I could have been in London to see this:
It walked around Whitehall!
It was apparently a piece of street theatre by “Royal de Luxe”, who travel around major cities performing this act. Skuds was there, and has a good write up. There’s a great flickr set here, which works well as a slideshow, a collective photo pool here, video of the elephant here – check out the ears! – and the remarkable puppet girl here.
I love that this exists.
