Only shared it via Show HN so far, and am still regularly getting some creative submissions. Will be sharing it at an art festival later this year so kids can have a more active role when visiting.

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.

There's a world of possibilities though, I hadn't even thought of combining color channels.

What I've found interesting so far is that sometimes the image plays a big part in the final video, but other times it gets discarded almost immediately after the first few frames. It really depends on the prompt, so prompt engineering is (at least for this model) even more important than I expected. I'm now thinking of adding a 'system' positive prompt and appending the user prompt to it.

Otherwise it's similar to the way nine women can make a baby in a month. :)

This is using the default parameters for the ComfyUI workflow (including a negative prompt written in Chinese), so there is a lot of room for adjustments.

I was running into OOM issues with Wan 2.2 before, but I found the latest version of ComfyUI can now run it (using about 17 GB of VRAM for what I assume is a quantized model?).

I'm currently hosting a video generation website, also on a single GPU (with a queue), which is also something I didn't even think possible a few years ago (my show HN from earlier today, coincidentally: https://news.ycombinator.com/item?id=46388819). Interesting times.

I created a simple website which lets children (of all ages) sketch something and then animate it using AI. It's a small hobby project because I wanted to see what all the hype is about.

No account required (but because the sketch app allows image uploads and we all know we can't have nice things on the Internet, I will be moderating the submissions before showing them on the front page).

Stack: Excalidraw, Django, Postgres, Redis for caching, ComfyUI for the image to video workflow (Wan 2.2 14B I2V).

Let me know what you think. Merry Christmas!

On the way, I developed lightweight image editor and 3D model viewer components, which I've open sourced [1].

I have to say I quite like it for more complex interactive components like this one, but still much prefer django with some htmx + Stimulus JS sprinkled in for the rest of the website.

It supports rotating, flipping, cropping, adjusting brightness and contrast, as well as adding arrows, circles and text. A major feature is that it checks for the maximum canvas size (which, as I have discovered, conveniently differs between browsers) and resizes the image to fit, so it supports editing larger images as well (an important point, as many users were uploading JPEGs straight from their camera and getting a blank canvas).

You can try it online for free (all processing happens client-side, without any tracking) at: https://photo.kigun.org

Please let me know what you think. Thank you!

This resulted in another side project, https://mishmash.photos/ -- a website to organize, share and collaborate on albums (because I always lose photos when going on trips with friends). There are better apps out there for this, but this one is mine.

Sample album: https://mishmash.photos/share/84f83b09-0a24-4d13-b436-8131ee...

Tech stack is django, htmx, bootstrap and a Stripe integration, to keep things simple.

(There's no free tier; from reading this website I know offering free image upload usually ends badly.)

The problem with the interdental brushing video specifically is that we can't show how to use larger brushes on young healthy patients, as they don't have the spaces for it. But I will think about how we can improve that video (the comment above suggested moving it down in the page, to start with the 'gentler' videos).

I wanted the interdental cleaning part to come first, because it usually gets neglected and it's just as important as tooth brushing.

But I like your suggestion to change the order, as that would indeed give a gentler introduction.

Good job with your daughter! FYI, we are working on expanding the instructions to children, so watch this space ;)

Generalizations are usually not helpful, I think it really depends on the dentist. I'm not sure there are proven benefits to oral microbiome testing, except in some very specific cases.

> The most significant cause for caries is S. mutans.

The 'Beyond Streptococcus mutans' section in TFA explains that the situation is much more complex than this; even if it is, good oral hygiene and reduced sugar intake (both in quantity and frequency) are still the best way to reduce the amount of biofilm present on teeth (which is a requirement for caries formation, whether S. mutans is there or not).

> Diet is the most significant way to affect gum disease.

The current clinical treatment guidelines for periodontitis[1,2] only mention that the benefit of weight-reducing diet and lifestyle changes is unclear (for treating periodontitis, obviously), and that oral hygiene is still the most important thing you can do yourself for the prevention, and, once established, to assist in the treatment of the disease.
