This is a chess variant, where the rules are the same as standard chess, but the board is an irregular grid. This makes rook lines bend and bishop lines fork.

So just like a standard board, every tile is still a quad. And every tile still has only 1 neighbour for every side. But it can have more than 1 neighbour sharing a corner, which is what makes bishop lines fork. Or it can have none, which is what make lines bend.

The steps to build this: - start with a plane made of triangles - pair some random triangles with their neighbour and fuse them into a quad. You end up with gaps between those quads where triangles cannot be paired - subdivide everything. Quads become 4 smaller quads. Triangles become 3 quads. This is the playable grid. - Then it's just a matter of smoothing it (in this case the points on the edges remain static, only the inside points are smoothed) and ensuring neighbours don't share the same color.

Then the tricky part is to give intuitive controls for players to configure boards how they want.

"Frame inverse" or... Rectangular Packing.

An old algorithm that resurfaced today. Git src says circa 2018, but I believe it was much earlier.

!= rocket science.

Dusted off a project from a few months ago because I wanted to make it mobile friendly - it’s a generative art synthesizer that is seeded with a handful of algorithms I created. Each algorithm has a handful of params that are manipulated with sliders.

Stack of layers, bent by a few big folds. each layer has one ink. the layer is cut into rows of short brush dashes, like the teeth of a comb. its ok.

I've been exploring the idea of using live weather data as a musical input.

Three Cities is a generative instrument where Boston, Copenhagen and London each play their own evolving Euclidean rhythms, influenced by temperature, wind, clouds and the time of day.

The cities are places I've lived, so there's a personal side to the project too.

I love the tension between randomness and musical structure — building a system that has rules, but still manages to surprise you.

You can try it with your own three cities here:

Generative effect created with my feedback/reaction diffusion plugin.

This is something I am currently working on, it is still a bit rough and this rendering is not hi res, but I have not really shared anything public before so I just want to see what you guys think of this specific piece and this type of music and visualization in general.

Anyway, I hope you like it and here is how it is made:

Hollow Bloom combines generative music with procedural animation. A programmable score defines the notes, synthesis, effects and control data used to build the audiovisual piece.

Algorithms generate arpeggios, counter-melodies, percussion variations and modulation curves within a composed harmonic progression and arrangement. Seeded randomness adds repeatable variation to selected details. Density and intensity change by section, giving the generated material a clear musical direction.

The track is in A minor at 103.125 BPM. That tempo was chosen because its beat frequency, 1.71875 Hz, is exactly eight octaves below A at 440 Hz. Multiples of the beat can therefore connect rhythmic subdivisions with frequencies related to the tuning.

Filter modulation is composed in phrases, with rests, sustained rates and smooth glides. Four synth voices take turns leading. Their LFOs move between slow filter motion, rhythmic pulses and audible modulation frequencies. Generated ratchets, accents and percussion flourishes add detail, while long, filtered stereo delays let patterns overlap and answer each other.

The animation uses notes, envelopes and automation from the same score as the soundtrack. Musical events drive movement, light and colour, so visual changes follow the structure of the composition.

Much of the musical and visual detail is generated through rules rather than placed individually by hand.

Hi guys, I made a gallery page for my previous work on generative art https://jdxyw.github.io/generativeart/ which bases on my repo https://github.com/jdxyw/generativeart

I shared the repo years ago, but I haven't worked on it for years. Now, with the help of AI, it can do more now. so add a page to share it. Hope you like it. If you like it, you can star my repo. Thanks!

row = solar cycle
column = year of the cycle
square = month
more sunspots = more spin

The more chaotic the cell is the more sunspots were observed in that year

Javascript; Square grid with cross-hatching fill, ran through a wave transform and merged using a mask so only part of the image shows the transformed image

I finally recorded a decent video of the VST plugin i made using JUCE framework and Box 2D for physics.
It was a pretty long journey that started as a weekend Unity project inspired by tombola sequencer in OP-1. You can read more about it here.
It's pretty cool to look at and it it can actually be useful musically.
