Makes sense, so it's an exercise in efficiency and crafty creative use of shapes and keyframing. I wonder if the ability is within reach of AI to achieve a similar arrangement of CSS. It may be too hard due to the trial and error nature of making these. Prompt: "give me CSS for an animated column of rising smoke, 5 second duration, seamless loop."
The fun part about this "exercise" is that the final graphic is usually created just by iterating and eye balling your mistakes. I remember the most I did back then was to create a Snowman and it took me more than 1 hr.
