Transparent small images over squares. Is this already done before?

I have seen this image shown below, and then I thought that is of course possible to make in Filter Forge, and would be a good idea, and use any kind of transparent background images or photos to fill the squares.

I wonder if a filter like this has already been done before and is available, or if not I could be able to make one, as this I think would not be very difficult to make, and does not need to know complex maths or any special FF components.

And possibly it could include also the ability to add textures to the squares.

Here is the example I have seen that could be the model for the filter if it is not already done and available

and this other one

and with real photo flowers now

And changing the background for different colors and still having a small frame

I like the last two examples the best
