Dancers

A small cafe close to the ferry dock changes the "displays" on the side of the building now and then, and I've blipped a few. This is a new one. I'm sure there's some significance or meaning in the image, but I don't know what it is and there was no one around to ask.  Anyone know?
Neighbour Bill's birthday yesterday, so we took him out for breakfast. I did a couple of hours work in the garden, starting to get the beds ready for planting. Great to get my hands in the dirt!
