Using only HTML and CSS, with no JavaScript, SVG or images, make a cup of coffee with a spoon stirring round and round inside it.Frozen at v1. This model got this and nothing else.
HTML and CSS alone, a continuous loop, and a cup seen from slightly above. The file is read for the brief and for the loop: an @keyframes rule that changes a position or a transform, named by an element, with the iteration count set to infinite. The picture is four moments of the animation, left to right, taken at 0.4 s, 1.2 s, 2.0 s and 2.8 s. Whether the rim reads as an ellipse seen from above, whether the spoon passes behind the far rim on the back half of its circuit, and whether the handle stays on the bowl are judged by eye from the page the run rendered, with the four frames as a first look. How it is scored, and this run's files on GitHub.
