genuary2021
A small collection of JavaScript programs with visual output written for the #genuary2021 challenge on my instagram. Click on the image to visit a demo or use the link in the the title to get the code for each sketch. I used p5-js as my main renderer and these self written tools: p5-toolkit, p5-glitch-effects, colorful-stripes. All examples are stored in genuary2021 and hosted live as github pages here.
All Challenges
2021-01-01 | Triple nested loop
In this program explored the flow of a triple nested for loop in a webgl canvas. I create a three-dimensional grid of boxes in the center of the canvas. Each box is rotated and scaled with a value from the noise() function to get this fluid look.
2021-01-02 | rule 30
I went for the standard 2D implementation with a initial randomly seeded row and then took it to 3D. I render cells that are alive as textured boxes and dead cells as textured planes. I modulate the height of the boxes with 2D noise for decorative reasons.
2021-01-03 | Make something human
During the lockdons due to the corona virus I missed seeing my human friends in real life the the most. When feeling lonely I’d take an A3 page and doodle large imaginairy faces with a big brush and acrylic paint. I’m not such a good painter, so I didn’t share these portraits so far. For today’s challenge I overlay the images with effects from my javascript library and gave them a final touch in the digital world.
2021-01-04 | Small areas of symmetry
I traveled along random angles of a circle and at every angle sketched a rectangle on the page. Using my function sym() I cut small areas of the canvas and show the image next to a reflected version of itself.
2021-01-05 | Do some code golf!
How little code can you write to make something interesting? I made noisy black dots.
2021-01-06 | Triangle subdivision
Wrote several functions that help me get this simple animation done. The geometry you see is calculated from 3 given vectors and rotated, styled and diplayed in a p5 WEBGL canvas.
2021-01-07 | Generate some rules, then follow them by hand on paper
Take a paper
Take a pen
Move at a random location
Pen down

2021-01-08 | Curve only
Inspired by floral drawings and minimalist aestethics I imagine a wild composition of blades of grass in a virtual landscape.
2021-01-09 | Interference patterns
Simple circles moving on the screen shape beautiful patterns.
2021-01-10 | TREE
I took a pen and sketched a landscape with a lone tree in the center. I imagine each branch would grow more branches, rotated by an angle. This is the classic recursive implementation, similar to the examples available online, but in this one I took great attention to the rendering. I designed the braches to respect the level of recusion. A semi-random structure of leaves with polygons remind f foliage. To give it more depth I added a ground and a sky. For these I used horizontal lines modified by perlin noise to get that hand-drawn, sketchy look I wanted.
2021-01-11 | Use something other than a computer as an autonomous process (or use a non-computer random source).
I didn’t have a quartz to swing nor a sensor. Also I didn’t feel like throwing a dice so I used two abitrairy landscape images as a lookup table. I measured all brightness values and divided by 255. What I end up is a single array with floating point numbers between 0 and 1. These numbers I used as a scaler for the radius of point rotating on a circle.
2021-01-12 | Use an API
“I let go of what I was holding onto”. In these images I combined the Google Fonts API and my glitch effects library together.
2021-01-13 | Do not repeat.
A rather impossible task in programming. I kept repetitions it to the bare minimum in this short program. I did not use for loops, while loops or recursion. I’m using three different shapes, too not repeat myself too much. It’s a very simple geometric composition, but the colors are randomly chosen from a list with three defined and one generated color.
2021-01-14 | SUBDIVISION
Hard to explain and very long, but basically a polygonized subdivison of a virtual circle segemented from the outside to the inside
2021-01-15 | Let someone else decide the general rules of your piece.
“Make snowflakes, each one different”, requested by Sabine led me to this abstraction. I started of a simple class wrapping a randomized polygon, that can fall down. Then I made a system of many falling flakes, each flake with a different speed. As the flakes fall they leave colorful traces on the canvas resulting in an eveer-changing graphical image.
2021-01-16 | Circles only
A noisy and moody animation of points along a circle
2021-01-17 | Draw a line, pick a new color, move a bit.
Flowing curvy lines with a 2D Perlin noise field, picking a random color from a list.
2021-01-18 | One process grows, another process prunes.
Shrinking the radius and increasing a random offset while the animation goes on
2021-01-19 | Increase the randomness along the Y-axis.
Used noise to create colorful lines that dissolve into points in the lower half of the composition.
2021-01-20 | No loops.
I used quite a bit of recursion and perlin noise multitplied by a small value to create today’s images. Otherwise this is built from my recursive tree example, but uses circles on the calculated endpoints. The script seems unpredictable but produces beautiful complex images.
2021-01-21 | The function f
This time I had to modify the given function f and added an exit condition to prevent too much recursion. After that and keeping my sanity I started jamming with circles and colors too make this geometric image for you after all.
function f(x) {
DRAW(x);
f(1 * x / 4);
f(2 * x / 4);
f(3 * x / 4);
}
2021-01-22 | Draw a line. Wrong answers only.
For today’s program I refactored an older line graphic program (2018-2020) to use the color-scheme I have been working on latley. The script allows you to draw lines with your mouse, but not like you would expect. A certain number of randomly orientated unit vectors is multiplied by a randomly picked constant length. All generated lines are tested and only those that do not intersect an existing line-segement are permitted in the graph.
2021-01-23 | #264653 #2a9d8f #e9c46a #f4a261 #e76f51, no gradients.
I used todays colors on rounded rectangles in a perfect loop animation. The design is my own thing but I used a tutorial read (link below). After having the basic structure down I modified it with 2D noise and trigonometric functions. A for loop is going over the all colors and uses the numbers to render this colorful animation on stage. Used ffmpeg over the command line to convert the image output to this video.
2021-01-24 | 500 lines.
In color, with noise & animated. :D
2021-01-25 | Make a grid of permutations of something.
Unexpected results to come, the future is ahead. I started with a grid and ended with a diffusion-limited aggregation pattern in color.
2021-01-26 | 2D Perspective.
A randomly generated arrangement of colorful boxes in a WEBGL canvas appears to me like a perspective view in an asian megacity at night.
2021-01-27 | Monochrome gradients without lines.
Wrote a function that returns an image with a linear gradient from black to white. Then used it in a composition loop.
2021-01-28 | Use sound.
This images visualize the frequency spectrum of live audio input over time. I reworked the p5.sound example code from a linear to a circular design and don’t clear the background. As an input sound I used the smooth pop song “Night Train” from https://soundcloud.com/buebuemusic
2021-01-29 | Any shape, none can touch.
Colorful circles growing in a circle until they touch any circle inside a circle.
2021-01-30 | Replicate a natural concept (e.g. gravity, flocking, path following).
I refactored the demonstration of Craig Reynolds “Flocking” behavior by Daniel Shiffman to a non animated, colorful version that gives me a single static image every time I call it.
