Bubble Tori and Barrier Penetrations
An artist Fernando Garrido uses bubbles to represent tori.
More examples of his work are here: https://ca.pinterest.com/search/pins/?q=Fernando%20Garrido
Image A has two barrier penetrations, through the line of little tori. It is equivalent to image B and C, where cone shapes mean an upward flow. Image D uses lilies, so it is a downward flow barrier penetration. On Mr. Garrido's art, bubbles/tori are also travelling through the various tubular shapes of the hats.
Flux tubes are an accepted science of magnetic energy flow, whether in our-reality's density range, or in higher-density flux. Nature knows how to make tubes, and this surreal art is trying to show us that little tori is what travels in those tubes. My post about the pisces symbol showed what I think is the same concept, little circles, little dots, or little stars, travelling along tubes. https://www.facebook.com/share/p/19dzbLQLcY/
Anyway, barrier penetrations are great fun to start noticing. Here's a collection: https://ca.pinterest.com/stevenbhalls/barrier-penetration/ But keep in mind that the barrier is interlinked little tori that are so small, they are likely mostly not in our-reality but in the surrounding higher-density. That's why a "bubble" membrane is a good analogy, being very thin and transparent.
