This AI image-to-video from Pika Labs. You provide a single image and a text prompt and roll the dice. It's implemented as an online service via a discord bot so you sometimes have to wait a long time and there is NSFW filtering.

This was one of the only results I managed to get with a coherent movement that didn't morph into something strange. Most of the time you get the windy hair/fabric effect applied to random parts of the image or no animation at all.

Maybe if it could run locally, you could run it hundreds of times and cherry pick good results, but as it is now, it doesn't seem to have any use at all.

Obviously someone opened a window, letting in a warm summer breeze.
