An HTML endless runner under 900 lines without frameworks or libraries
My wife and I recently submitted to a mobile game jam on Newgrounds (yes, it's still around). What started as a question of whether we could do it somehow morphed into whether we could do without so many of the seemingly needless complications rampant in our respective industries. My wife thus did all the art as traditional frame-by-frame animation (no puppets or tweening) and I preceded without a game engine. I did use a pre-processor that gives JS a Lisp syntax (Parenscript), because C-syntax is gross. We hope the end result, while definitely of small scope, will serve to inspire some…
In plain words
An HTML endless runner game built with plain JavaScript in under 900 lines of code, without game engines or frameworks. The project features hand-drawn frame-by-frame animation and uses Parenscript, a Lisp-syntax preprocessor for JavaScript, to simplify development. Created for a game jam, it demonstrates how to build functional games while minimizing unnecessary complexity and tools, making it useful for developers interested in lightweight, minimal-dependency game development.

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:…

Hey HN, I've been working on https://pornpen.ai, a site for generating adult images. Please only visit the site if you are 18+ and willing to look at NSFW images. This site is an experiment using newer text-to-image models. I explicitly removed the ability to specify custom text to avoid harmful imagery from being generated. New tags will be added once the prompt-engineering algorithm is fine-tuned further. If the servers are overloaded, take a look at the feed and search pages to look through past results.
