PDCA – Public Displays of Cephalopod Affection

Sometimes the easiest way to spark discussion about science is to bring it into everyday situations – like by wearing it as jewellery.

Steampunk cephalopod by Noadi.

This week polymer clay sculptor Noadi a.k.a. Sheryl Westleigh aims to increase the conversation about cephalopods – and it’s Cephalopod Awareness Days!

Cephalopod Awareness Days are organized around the number of limbs of these charming molluscs:

  • October 8 – Octopus Day, for all the eight-armed species
  • October 9 – Nautilus Night, a time for all the lesser-known extant cephalopods
  • October 10 – Squid Day/Cuttlefish Day, or Squittleday, covering the tentacular species
  • October 11 – Kraken Day, for all the fantastical cephalopods of myth, movies, literature and legend. Cthulhu fthagn!
  • October 12 – Fossil Day (to coincide with National Fossil Day), for all the incredible suckers that have gone extinct but left an impression with us.

Noadi is doing contests and giveaways on her blog for a couple of more days featuring her fun (and just a bit sinister) tentacles creations. I can’t see how any of these would fail to spark a conversation at the grocery, in the lab, at holiday dinners, or when waiting in line to cast a ballot.


Deep Space Nautilus by Noadi


While many of her creations have bright colours, I love how the greys and metallics look on the soft twisting forms.

A custom piece , part of a steampunk series.

Look for tutorials on her site too.

The versatile Noadi has a deft hand at painting too.

    Thank you so much for the feature! I can certainly attest to my jewelry sparking conversations, I have a blue ringed octopus necklace that I wear on a regular basis when I go out and I’ve had so many people ask about it and end up talking about cephalopods. When I started making the jewelry I never thought it would lead to being an impromptu science teacher as often as it has which has been a huge, and very pleasant, surprise.

    Noadi, that’s one of the important things about art and science-inspired art in particular. It needs to among people, not hidden only in elite galleries for tiny audiences.

    One of the greatest things is making art for a scientifically-literate audience who gets it. The other is making it interesting enough for everyone else to start asking questions.

    theFabulous0ne: Glad we could help you find more of your favorite!

    Is H. P. Lovecraft a posthumous guest?
