I can't play an instrument, so I worked out music theory from first principles in JavaScript instead, starting from a single oscillator.

Every example is editable and runs in the page, so you can change a number and hear it. No audio libraries, just raw Web Audio.

Ever wanted to explore holographic projections in software? I'm developing HoloField, a modular framework that projects 2D math into 3D geometry. Even though it's a work-in-progress, you can already use it to experiment with your own custom mathematical formulas and 3D transformations.

The code is on GitHub. Search for ngdias or Holofield, I'm not sure I can post links here.

I didn't draw any of the base art
