Last week I was driving from an appointment through some pleasant country lanes and stopped at a layby to make a couple of phone calls (while there was the briefest of signal) and on the ground was a strange wooden item.
So I picked it up, examined it, was confused and so I brought it home. I have no idea why it was there and don't know what it is. See the video below for a demonstration... you twist the middle and the two layers of 'petals' open up. It's more than an ornament, it actually does something.
