In my opinion see [screenX screenY equivalent in p5.js](https://discourse.processing.org/t/screenx-screeny-equivalent-in-p5-js/10581/5)

so it’s another way of picking: each cube stores it’s 2D screen pos.

When the mouse is clicked, check mouseX,mouseY against the 2D screen pos using dist() command
