These sorts of CSS experiments have been around for as long as CSS. There even used to be a site where an entire community would take basic markup and use CSS to turn it into something else.
(I just googled that phrase - the site is CSS Zen Garden. It’s impressive Google found it because that was a bad search.)
Some people did create monstrosities, others learned the limits of CSS and used that knowledge to advance CSS. So my point is that I believe in the ability of people to advance through discovering all the things they shouldn’t do.
CSS Zen Garden is not an experiment as shown in the title of this post. The Garden shows how CSS can style the HTML elements in many different ways but it is not there to create or manipulate images as shown in the subject of this post.
That said, I have not looked at the Garden in many years so if you fine one, then you found .... one ... and I loop back to my original comment: that such things are impractical, it's not what CSS is for, and should be avoided.
In other words, you don’t learn through experimentation and your learning style is the only valid one? Okay…this isn’t worth debating but science has proven that to be wrong.
