Rotating Crosses

Celestial2/2⚠️

This code creates a graphical design on a canvas.
When the mouse is clicked, the design is redrawn on the canvas.
Each time the design is drawn, the shapes within it are rotated randomly by a multiple of 90 degrees.

The design consists of a grid of small cross shapes, made up of rectangles and lines.

Additionally, the "s" key can be pressed to save the current design as an image file.
