It would be cool to have a cloak with an animated portal from the show Rick and Morty. The two designs would be animated so that the portals would move how they do in the show. One cloak would have a green portal, (Rick's portal), with a black background and the second cloak would have a golden portal, (Evil Morty's portal), with a white background. The designs would be very simple as would the animation. As far as copyright goes from what I know currently.. pictures, gifs and animations of things from the show are fine to use anywhere as-long as a clip of the show isn't involved.
The cloaks would have both portals directly in the center as if you were standing right in-front of them. It's a small idea but there's a big target audience when it comes to Rick and Morty themed stuff and there will definitely be a strong appeal to the designs.
