Would be possible to create this Sphere of Spheres in FF?

I have seen this image that is attached below and thought that I this could be done with the Gradient Circles by Skybase perhaps making a selection, BUT I was wrong because I did not think that of course the textures will be cut at the selection edge and nothing will be out of the selection.

Perhaps there could be a way if the gradient circles filter did not make the bubbles/circles if the background was transparent.

Another possible way is to render the textures and then delete by hand all the circle/bubbles that were outside of the ball but this is too time consuming and very difficult to do.

Then I thought that could render a 2D version and use the Spherical Projection by inujima but this does not work as the bubbles/circles are deformed by the projection distorsion

So I am asking if anyone knows if this example below really could be possible to be done in FF in some way

well done Skybase! Very good how you have done this.

I am sorry that I am not an expert like you, and it could be easy for you, but I have been thinking on how to make a masking or something similar to make this and I have not yet found the way.

Well. let´s see if it is simple and easier, I could use the Get Alpha to detect the transparency and then be able to make a mask so it does not show the circles on the transparent parts.

and this is with a circle

So what have you changed?

Some more modifications with the new setup....

Well, this may be the easy solution for you because I would never have imagined this, when you said "Think simple", I have done just that and found a simple fix.

WOW!! The new version looks really much better and makes really excellent, amazing and awesome bubbles/circles based on the source, I like them really much. Congratulations on this new version.

Thanks very much for taking the time to make this new much better version that looks so good.
