A playful audio-visual party for you and your computer.

"It doesn't matter what you wear, 'cause it's only gonna be you and me there."

~ Shania Twain - Party for two

Party:4:2 is the perfect occasion to get some one-on-one time with your computer.

Your computer brings some music and some lights and you bring yourself.


What are you talking about?

This is a little art project.

More material (hopefully) coming 🔜.

Run and build this

To run this locally install dependencies with npm or yarn and then either:

$ yarn run start to start the dev server (opens browser window automatically)


$ yarn run build to build into dist.


I'm using a small music generator that I wrote to generate melody snippets on the fly.

I wanted to use contro for handling user input from a gamepad with keyboard fallbacks. Sadly I didn't get it to work with my controller, so I wrote some wrapper code myself. But I would like to change that in the future.

The visuals are done in WebGL, feeding sound FFT data directly into the fragment shader. The webgl environment setup lives in lib/shader.js, the shaders themselves in lib/shaders. I thought performance would be decent, but I was wrong. I'd also like to revisit that.

Thanks and credits

I want to thank the ProcGen community for writing a lot of stuff about procedual generation so people like me have a starting point for weird ideas. Especially the article on Procedural Music Generation that made me want to give it a shot.

I want to thank all people who work on open source software, because it's a beautiful thing that we have <3
