Show HN: Fun sketch – Bring your sketches to life (opens in new tab)

Nice work! What hardware are you running ComfyUI on, specifically the Wan2.2 workflow? It must be expensive having a GPU running for a hobby project like this?

Thank you everyone for taking a look. The website had around 1,200 visitors and received over 90 sketches over the past 24 hours, and I'm happy to say I could approve almost all of them (all except 2 'rocket' sketches which were starting to look a bit dubious, but all in good fun).

The results look very interesting to me, and I think as a next step I will look into adjusting the prompts (both positive and negative). On the one hand, I'd like to keep the sketch/drawing look rather than going full photorealism as some of the videos do, on the other hand I don't want to restrict the users' creativity too much.

I plan to simplify this further and optimize it for tablets. Some friends said they'd like to have their kids try it out it and I like the idea, as by having to sketch it keeps the user in a more active role.

Please let me know if you have any other suggestions.

Pretty good, I've noticed the animation tends to veer off / hallucinate quite a lot near the end. It is clear that the model is not maintaining any awareness of the first image. I wonder if there's a way to keep the original model in the context, or add original image back in at the half way mark.
