ANIMATED CIRCLES is a simple and interactive canvas built with HTML, CSS, and (vanilla) JavaScript.
Have a look on here, or in codepen.
On page load, 600 circles will be spawned. They will be moving at a random yet constant speed.
Move the mouse inside the page: circles close to the cursor will grow. They will revert to their original size once far from the cursor.
By double-clicking inside the page you will activate the "attraction" feature. Double-click again to disable it.
