Hughie,
maybe it's the sheen you've achieved, maybe it's the 8 full turn spirals, but probably it's the strange way I think and sometime see things ...
... but I look at this vessel and see the arms of an octopus wrapped around a pot, about to see if it can fit inside.
The spirals (arms) are thicker and more round in cross section than your vessels with more spirals, the mottled effect of the burr (burl) along with the sheen is the wet skin, the spiral (arm) tips reaching towards the hole.
I don’t know if it’s wrong to see what the creator did not intend, but the overall effect makes me see an octopus!
And because I can see something more in this form than those you’ve posted previously I think it is the most interesting, and for your work that, that is saying something.
A truly lovely thing to behold.
