Sure! Here is an example of a simple generative art game implemented as a single HTML file with JavaScript:
This HTML file creates a canvas element and uses JavaScript to draw generative art on it. Each frame, a random rectangle is generated with a random size, position, and color. The canvas is cleared before each frame to create the illusion of animation. The game continuously requests the next frame using `requestAnimationFrame` to keep the artwork constantly changing.
You can play this game by opening the HTML file in a web browser, preferably on a smartphone for a better experience. The art will generate automatically, creating a unique and ever-changing visual experience.
