Not every browser can draw it. The picture is made live by the graphics card — up to one and a half million particles at once — and not every browser lets a web page use it that way.

It’s built for a big screen. There are dozens of controls — sliders, audio, text and export — beside the picture. On a phone or a tablet they end up covering the very thing they control.

On a Mac or a PC it runs in Chrome, Edge or Arc, and in Safari on an up-to-date Mac.
