Artists did some wild stuff with it. A few fun examples:

(There were also a few INI-style config files, mainly to define colors of dynamic things like text. For most skins you would just need to copy the defaults and maybe change a few color hex codes.)
I remember them for rendering my computer almost unusable by eating up nearly all of the available compute... But my gosh it was pretty!
It's more difficult now than it was back then for KDE I guess, because with Qt Widgets, QML, and Plasma you basically have three times as much to support in a theme/theming engine. And then back in the day better KDE themes also provided themes for Gtk, so that Gtk apps integrated nicely. How many concurrent Gtk versions are now used that you would all have to support? And sometimes (especially non-Qt programs) take some colors from the theme, but not others, breaking everything when you want to customize your theme (you get e.g. black text on black background). So I appreciate the renewed effort, but I'm not holding my breath.

Why? Because I dont think most people ever actually cared about it. It became a "cool thing" to customize your MySpace or winamp, not something actually motivated by individual user behavior. The people calling for more customization options ignore the plethora of options available because what theyre wanting is a cultural shift, but everyone's attention is so divided that it feels like a waste of time to devote to something that doesnt bother you. You "miss" what you had despite never doing any work to understand it.
The Museum is great, though! Thanks!
All of these Winamp skins work perfectly well in Audacious.
Go on. Do it. It's not like you were doing anything else. Get it installed.
The code for the Museum as well as the Webamp player that powers the interactive preview can be found here: https://github.com/captbaritone/webamp

Thanks for flagging, I removed that A name record.
