A little side project, a watercolor art generator
Hi HN - this is a little side project I threw together. Some implementation details: image processing is all done with headless GIMP (running inside a Docker container) through its built-in Python API. It's _very_ slow (about 50 seconds/image), and currently it processes exactly one image at a time. The website is built with NextJS; payments are processed by Stripe. I've had the best results with pictures of houses, although certain photos of people or nature can look neat, too. (For example: https://brushify.art/s/ruYmQWk, original photo from…
In plain words
A watercolor art generator that converts photographs into watercolor-style images using headless GIMP for image processing. The tool works best with photos of houses or subjects with clear margins, taking about 50 seconds per image. Built with NextJS and Stripe for payments, it processes images sequentially. Users upload photos and receive digitally transformed versions with watercolor effects applied to the edges and overall composition.

(For example: https://brushify.art/s/ruYmQWk, original photo from https://en.wikipedia.org/wiki/Pillars_of_Creation.) The effect obscures the edges of the photo, so images with plenty of margin around the subject work best. Something I'd like to play around with is swapping the GIMP script for an AI-based process (maybe using something like Stable Diffusion?), with the goal of generating images that look more handmade (something like these: https://www.etsy.com/ca/search?q=watercolor+house). I have exactly zero AI experience though, so there would be a bit of a learning curve. Would love any thoughts or critiques! ---- edit: remove unrelated details

I've been working on a CSS Sprite generator for a couple of weeks in my spare time. It uses HTML Canvas and JavaScript FileReader to open local images without any zipping or uploads, and tries to make the CSS generation as easy as possible. I made it because it is a tool that I wanted to have, and I am hoping to get some feedback from others now that it is functional. http://instantsprite.com

I made a thing! In 2014, I was holding a stack of iPhones and thought to myself: "Hey, if I had each phone display a playing card, I could click a button and they'd shuffle themselves" I pared that idea all the way down to this: trading cards made of e-ink displays. Right now, each card costs me about $20 each, but with only a bit more scale, I think I can get that down to $10. In doing this project, I learned how to design electronics and circuit boards. I learned Rust and wrote my first driver, I upped my CAD skills, 3D printed, and did my first resin casting. I generated the images on the…
