1) Looping ad: Bright Dawn, Scorching Dusk, Lovely Night.
2) Same sub-brand, a different product each loop (swap 3 transparent PNGs).
3) Same product in a new colour each loop (blue, red, purple sneaker).
4) A different brand’s product, same template.
5) Loader: remove the product, add your logo, and the ship loops as a “sailing, wait...” loader.
6) Your own idea.
