I am creating a program for Ubuntu which should be able to display an image (probably animated) over the top of all windows, although if the image is over the top of a button on an application, it shouldn't prevent you from pressing that button, or interacting with anything else on the screen.
I saw that there was already a question asking about almost the same thing here Is there a way to superimpose a transparent image over everything that is displayed on screen?, although I see that that one was closed for some reason and did not receive any answers, so I am asking again. How could this be achieved? I am running Ubuntu GNOME 15.04.
