Finding images in the same set or style

Thanks Tom. That is a great suggestion! Tried it and here is the result -
Tineye didn't bring up anything and made the image background black for some reason, though good old google lens did the trick when I uploaded there. This and variations came up on a few sites where they are used. Then used the source search feature and found it on pixabay. Pixabay shows the tags which is helpful and I could find more using the term 'pixel cells' . I've attached an example, just fyi.

Thanks for your helpful suggestion.

Being able to see image tags in Articulate's library would be helpful too.
