Ultrasound?

Actually, NO!

This is one of many experiments (good old lock-down) I've been doing at home. A small set of spirit based inks in water, a few drops swirled around then play around in PhotoShop. I inversed the colours which accounts for the black background.

Quite amazing!

Very effective. It looks rather like an axolotl.
