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

### Runner game
`2024-04`
==video:"/media/musi_pi_soweli_tawa.mp4":"simple runner game, similar to the chrome dino game"

## rotary encoder keyboard
`2022-05`
[github.com/CrispyPin/rotary-kb](https://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](https://ldjam.com/), 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](https://github.com/ErikBot42). I have done both art and programming for all of them.

### LD50: Pixel Entropy

# shaders
Most of my shaders are made in Unity and uploaded as props for ChilloutVR. All my ChilloutVR props are in [this repository](https://git.crispypin.cc/CrispyPin/cvr-props).

### 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.
==video:"/media/shaders/qr_shader_bit_order.mp4"

### shader quine
`2024-08`
A [quine](https://en.wikipedia.org/wiki/Self-reproducing_program) 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.
==image:"/media/shaders/shader_quine_198x99.png":"a large square of shader code, being rendered by itself"

### 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.
==image:"/media/shaders/shader_quine_2877.png":"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.
==image:"/media/shaders/sunset_shader.png":"sunset over a calm ocean, with stars visible in the purple sky"

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

==image:"/media/shaders/julia_distorted.png":"bright purple julia fractal, with distortion"

## andriod
`2024-05`
source: [git.crispypin.cc/CrispyPin/android-shaders](https://git.crispypin.cc/CrispyPin/android-shaders)
Using the app [Shader Editor](https://f-droid.org/en/packages/de.markusfisch.android.shadereditor/), 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.
==image:"/media/shaders/binary_clock_square.png":"a 4x4 grid of circles, some of which are filled"

This 3-row version uses the traditional division of hours, minutes and seconds, just displaying the three numbers in binary.
==image:"/media/shaders/binary_clock.png":"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](https://git.crispypin.cc/CrispyPin/cvr-props/src/branch/main/Assets/raymarched/lib)

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

### spinny thing
`2023-07`
==video:"/media/shaders/rm_spinny_thing.mp4"

### flesh cube
`2023-07`
==video:"/media/shaders/rm_flesh_cube.mp4":"disgusting pulsating fleshy cube"

### big nut
`2023-09`
==video:"/media/shaders/rm_big_nut.mp4":"a spinning metallic bolt and nut continually screwing and unscrewing itself"

### loops
`2024-08`
==video:"/media/shaders/rm_looping_loops.mp4":"11 rectangular frames moving through each other smoothly":loop=true

### boxes
`2024-08`
==video:"/media/shaders/rm_boxes.mp4"

## cellular automata
### game of life
`2023-07`
I also made a web version of this in may 2021, see [gol.crispypin.cc](https://gol.crispypin.cc/?cellsize=10&time=2) or [github.com/CrispyPin/gol-wallpaper](https://github.com/CrispyPin/gol-wallpaper) for the source

### rule 110
`2023-09`
