Sākuru #1

According to Google translate, Sākuru means circle in Japanese.
In this project I take several circles and shuffle their pieces on a grid. While dragging them to their final position I keep their trails (or not).

The project is written in vanilla Javascript.

The drawing is executed at window resolution.

Press '2' to double the resolution. You can press again '2' to double once more;
Press '1' to get back at the window size.
Press 's' to save a png at the current resolution. You can also right click and 'save-as' to obtain the same result.

On mobile devices the program picks the device resolution for rendering (instead of browser available space). This will enable you to save it as png and use it as wallpaper.
