Neat! I recently wrote a weather app for System 3.x using autc04/Retro68[1]. I've been planning to create an original set of weather icons, so this is exactly the kind of reference I was looking for.

Going from memory these are all pre OS8? Scrolling through I expected to see a massive change when OS8 hit but I don't think this ever gets there. My memory might be faulty, but I did recognize the various flavors of 7.x. Surprising to see how long the OS6 aesthetic kept on. It was fun to scroll through and all the memories. Surprising how strong of an effect these icons had on me.

Felt a little betrayed to see it used powershell scripts to make the website.

It would be nice if popular ones were shown first. I scrolled through many pages and only recognized about 1 in 100, despite having used Classic Mac OS a ton through the late 2000s.

It would be nice if each one had some links to it

These are awesome I am enjoying going thru these and looking for inspiration!
