https://ibb.co/RbYRQLN i found this on the sources tab in the inspect window (right click on site, select inspect open sources tab and open random pause buttons until you find a green one called noise.png in the "gfx" folder). GFX means "graphical effects", and is a folder in the sources tab in the flipanim.com folder, idk if this was mistaken for a png file, but it seems kinda interesting.
