The program starts by randomly selecting a divisor of the canvas width & height and forming a grid of rectangles. 

There is then an 80% chance that these rectangles will be rotated by a randomly selected angle ranging from -180 to 180 degrees. The shape is then either assigned a solid fill colour or is rendered empty with a border width of 1 to 5 pixels.

Spicing up the outputs is a selection of 14 palettes, each holding 2 to 8 colours for the algorithm to pick from. There is a 30% chance of an output having a dark background, and 7 of 14 palettes are limited to lighter backgrounds.

During development I came across a bug which meant rectangles would render taller than anticipated, I liked it, so I kept it in. The extra shapes round the project up nicely as they collide with each other leaving a beautiful mix of colours and geometry. For fun, I also added a 40% probability of circles showing in the output.

I hope you enjoy it as much as I did making it."
