Cat Grimace Scale
A visual pain-assessment tool for worried cat owners
What it does
A simple web tool for comparing your cat's facial expressions with the five features used in the Feline Grimace Scale.
An online web tool for comparing your cat's facial expressions with the five features used in the Feline Grimace Scale.
A simple web tool for comparing your cat's facial expression against the five features used in the Feline Grimace Scale. You don't need to decide what "slightly squinted" looks like from memory. Each step gives you a visual reference to compare with your cat. Use a well-lit image where your cat's face, ears and eyes are easy to see. Your photo stays visible while you compare it with normal, mild and marked reference examples. See the five individual scores and your overall assessment in one clear summary. The Feline Grimace Scale uses five facial action units. We turn each one into a simple visual comparison step. Use this as a guided assessment aid. If you are worried that your cat may be…from catgrimacescale.online

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
