Nice visualizations - have you tried Rebelle? They have an online version that lets you play with the watercolor/brushes of the painting software so you can see the colors drying on the canvas.

As an amateur watercolour artist (shameless plug: https://www.instagram.com/p/DBlKG5cMPxa) I have to say the feeling your made with this wash is gorgeous. Back in the analogue world - paper grain and type/brand has a lot to do with it. Watercolour is really about unpredictability - it's about taking advantage of this unpredictability in terms of how the water travels down the grain and the impact that it makes, combined with light/shadow and "confidence" the artist brings with the brush. So of course it's never going to be truly transferrable digitally, but I still love the work you put into this.

The examples display a degree of vorticity that I have never seen in real life watercoloring. They look great superficially, but they look super weird at reasonable inspection. Water on paper does not flow nearly so freely.

Great example of a Single File Web App (https://gods.art/articles/single_file_web_apps.html). I'm trying to get a wikipedia page up for this concept (https://en.wikipedia.org/wiki/Draft:Single_File_Web_Apps).

Beautiful! Love the fluidity. Great for calligraphy.

While I've tidied up a bit, the rest of this article contains plenty of AI-witten prose.

This is the right approach. I have no problem with someone using AI to draft a presentation (especially a technical one like this) -- just say it upfront and then people have no reason to get upset.

looks beautiful! i wanted to bookmark it because sometimes i need to explain some geometry to my son, and i have to download some sketching app each time, but with this I could just open and paint. There's one problem however. When on mobile, the page does not hid the control panel (mode, ink, etc) and it takes a large portion of the screen.

The interactive explanation is the best part — being able to scrub the sim while reading the writeup made it actually click.

This is awesome! The strength of the flow/advection is a bit too high imo. Maybe increase some viscosity parameter?

This is really charming. The interactive demos make the technical explanation much more approachable. One feature that might be fun is replay/exporting the stroke process, since the wash spreading is part of what makes it satisfying to watch.

Very cool app and very well explained throughout! I enjoyed peeking under the hood and learning those details like sampling a lower res flow field. Thank you for creating and sharing this

amazing idea and writeup! The only missing piece is to make it PWA (make it open as 'normal' app, especially on a tablet pc) it takes just adding icons, manifest, service worker - https://gist.github.com/sigman78/f1d8ceaf645b4dd773ff7bcaf64...

This is so satisfying! I love how the blending looks and fluidly works.

I've always admired watercolor animations (especially the ones in the video game Gris) and wanted to bring that to the web, but didn't know how.

I like that adding pen strokes to a watery section continues to blend in. Ima copy you now and become a cool art person

this is really gorgeous. I build ed tech apps for kids, which often includes whiteboard. I am always in search of inspiration to make it more tactile and less MS Paint, love this!

Very impressive work, thanks for sharing!

It is very fun and aesthetically pleasing also, great job.

i like it a lot. looks beautiful

Why is just having the web page loaded in a browser's (Firefox) tab ramping up the iGPU on my computer to 75%? The GPU load is consistently 75% whether I'm drawing or just have an untouched web page.

MS Edge has the same behavior with GPU loading regardless of drawing or not, but the GPU is at 50%.
