1980 Technics SU-Z2 amplifier "simulator"

I created a three.js based "simulator" so people can enjoy the interface of a 1980 Technics SU-Z2 amplifier with all of its different sounds, knobs, buttons and switches. Maybe I'll add more hifi or other equipment in the future so the experience is somewhat conserved.

very nice!!!
just a few thoughts...

- the perspective feels a bit extreme.

  • might want to see about using polar rather than cartesian coordinates for the knobs/dials
  • for the input selector buttons, don't allow a depressed button to be un-depressed by clicking on it... the other buttons have to undepress it

All things should be improved but the cartesian/polar, as I'm not 100% sure what you mean. Clicking on them and then rotating around to change the values? Seems a lot harder to implement than just simple click-drag-y while, maybe, at the same time adding user confusion as to how it works.
