Portfolio

Hi, this is a non-exhaustive list of my personal projects. It appears I like making things with computers.
The dates listed are generally the last time any significant change was made, for projects that spanned several months.

hardware

Conways Game of Life

2024-04

Runner game

rotary encoder keyboard

2022-05
github.com/CrispyPin/rotary-kb
A silly project making a terrible input device. You select a letter by rotating right and left moving down a tree, and press to type it.

jam games

LD is the Ludum Dare game jam, where you have 3 days to create a game fitting to a theme that is revealed when the jam starts.

All the below games except for LD45: Mind the Gap I made together with Erikbot. I have done both art and programming for all of them.

shaders

Most of my shaders are made in Unity and uploaded as props for ChilloutVR. All my ChilloutVR props are in this repository.

void sphere

2024-09
My first time making a vertex shader, it generally works on any simple mesh.

hilbert worms

2024-09
Little worms following the hilbert curve

partial QR code

2024-08
A shader that can display qr codes of any size, though it requires computing the error correction codes beforehand. Partially because it would be slow to do for every pixel every frame, but mostly because I couldn't find a resource explaining how to do it.

shader quine

2024-08
A quine is a program that outputs its own source code. Since shaders don't have text or file outputs, a shader quine must render its own source code instead. This shader contains the font data required to be readable.

shader quine golf

2024-08
Code golf is the art of shortening a program as much as possible while still producing a required behavior. I made a tiny version of the quine, only 2877 bytes large. At the end it does render some random characters, but I still consider it valid. When code golfing, undefined behaviour is part of the fun.
a smaller wall of text, with a low-resolution font that is just barely readable

sunset

2023-02
This is a single fragment shader, which means you can put it on any mesh and it will look the same.

julia fractal

2023-07
They are both animated slowly, but the second one has distortion based on world position.

andriod

source: git.crispypin.cc/CrispyPin/android-shaders
Using the app Shader Editor, I made some shaders for my phones' wallpaper.

binary clock variants

2024-05
The 4x4 version divides the day into 2^16 sections, each one about 1.3s long, and displays the number of sections passed since midnight as a binary number.

This 3-row version uses the traditional division of hours, minutes and seconds, just displaying the three numbers in binary.
3 rows of 5, 6 and 6 circles

raymarching

libgarbage

2023-07
libgarbage is my raymarching shader library, with which all the following shaders are made with. It doesn't have its own repository right now, but can be found in git.crispypin.cc/CrispyPin/cvr-props

libgarbage demo

2023-09
An example scene made for libgarbage, showing most of the primitive shapes available.

spinny thing

2023-07

flesh cube

2023-07

big nut

2023-09
I am very mature.

loops

2024-08

boxes

cellular automata

game of life

2023-07
I also made a web version of this in may 2021, see gol.crispypin.cc or github.com/CrispyPin/gol-wallpaper for the source
Conway's game of life

rule 110

2023-09
See Elementary cellular automaton (Wikipedia).

WireWorld

Lenia/smoothlife

godot

voxel raymarcher

utilities

These programs are less flashy and were made out of necessity. I don't expect anyone else to want to use them, but they are available if that was the case.

snoud

2023-02
source: https://git.crispypin.cc/CrispyPin/snoud
A simple terminal app that plays multiple audio files on loop, meant for background ambience. I use it for rain and wind sound and have it auto-start when I log in.

htmd

2024-09
source: https://git.crispypin.cc/CrispyPin/htmd
This is the markdown to html generator that this site is built with. It uses markdown as a base but is far from standard markdown, it has weird quirks and macros that I needed.

webserver

2024-07
source: https://git.crispypin.cc/CrispyPin/webserver
Made at first to learn, then to run this website. It seves files and supports partial requests, allowing you to watch videos without needing the whole file to be cached first. (videos are still partially broken, only some formats work properly)

julia fractal renderer

2023-07
source: https://git.crispypin.cc/CrispyPin/julia-fractal-renderer
I used this to generate the image printed on my deskmat, seen in the picture of my keyboard
(see source repo for more examples)

brainfuck debugger

2023-12
source: https://git.crispypin.cc/CrispyPin/bf-debugger
When I was solving some Advent of Code problems in Brainfuck, I found myself missing the ability to set breakpoints and step a number of iterations through the program, so I made an interactive brainfuck debugger.

I used this to develop solutions for part one of day 1 and 4, in advent of code 2023. These can be found here: https://git.crispypin.cc/CrispyPin/aoc-2023/src/branch/main/bf

text editor lili

2023-03
source: https://git.crispypin.cc/CrispyPin/lili
lili is a terminal text editor that can keep multiple files open. It is far from perfect, it doesn't handle soft linebreaks well and lacks undo/redo. But wider characters at least work (tabs and emoji).

compiler-timer

2024-01
source: https://git.crispypin.cc/crispyPin/compiler-timer
At work, I was frustrated by 20-45 minute C++ compile times, so I made a compiler wrapper that keeps track of build times, and tells me the average time wasted per day.

Example output

(regular compiler output)

Build took 18.025s
Total wasted today: 44m 5s
5 day average: 35m 38s
Overall average: 40m 22s
Since 2023-09-07: 55h 11m 22s

neuralblender-mc

2021-09
https://github.com/crispypin/neuralblender-mc
This was before the "AI" hype bubble became as obnoxious as it is now. I found the website neuralblender.com (no they don't deserve a hyperlink), which generated quite terrible images from a text prompt. There was no information about the website anywhere.
I made a stupid input-emulating script that ran in a vm and generated textures for every texture in minecraft 1.17.

The cursed flowers in the picture below are poppies, which for some reason resulted in a blue-haired cryptid in the corner.
