Here are some links to websites related to this one, whether they're similar in content or I just plain liked them.
This is a page that actually doesn't work in older browsers.
But I promise that it's unique in that aspect... I spent a whole lot of time on the JS here and am unwilling to rework it all from scratch (at the present moment, anyway).

If you have a website that belongs under one of these categories, drop me a line and I'll add it; new pages will be added in dubiously-frequent batches.
Coupled with the fact that it has a considerable number of links, this means that this page is perpetually

Webpage/Graphic Design

Resources related to webpage design and graphic design.

Webpage Design

W3Schools ┊ w3schools.com
⮡ Know absolutely nothing about HTML, CSS, or JS, but want to start coding your own webpages? Start here!

Notepad++ ┊ notepad-plus-plus.org
⮡ A great text editor for writing said HTML, CSS, and JS. I'm making this very website with it.

Graphic Design

Computer Graphics Stack Exchange ┊ computergraphicsstackexchange.org
⮡ Is what it is. I recommend just searching for your question first instead of making a new post of it (if possible). All I'll say else is that I usually leave with my Photoshop question answered!

Fontspace ┊ fontspace.com
⮡ A good-and-reliable place to find fonts. (You won't get duped into downloading and using a font that wasn't actually free and subsequently find yourself in legal trouble.)

Ænigma Fonts ┊ aenigmafonts.com
⮡ An archived capture of the (now-gone) Ænigma Fonts website. Ænigma created lots of cool fonts, one of which is Detonate BRK, the font you see plasted all over this site in #cf0.

WhatTheFont! ┊ myfonts.com/WhatTheFont/
⮡ WhatTheFont! is a tool that helps you identify a font from an image of it. It kicks ass when you're trying to recreate something or its aesthetic.

Unsplash ┊ unsplash.com
⮡ Unsplash is a website full of 100% free to use photos. Like Fontspace, it provides a practical resource while keeping you out of unforeseen legal trouble.

Old Web/Computing

Resources related to the old web and old software, firmware, hardware, etc.

Old Web

Wayback Machine ┊ archive.org/web/
⮡ There's no way you didn't already know about this one, but it's so important that I still wanted to list it. The Wayback Machine is a massive collection of captures of webpages in the past, recent and archaic alike.

GifCities ┊ gifcities.org
⮡ GifCities is a search engine that combs archived GeoCities sites for GIFs matching the keyword(s) you enter. A very easy way to find the old-fashioned GIFs that you seek.

OoCities ┊ oocities.org
⮡ OoCities is an easy-to-browse GeoCities archive, organized similarly to GeoCities itself. I used it to find the pages listed under the "GeoCities Selects" tab here.

Emulation

I've put this section above the following two because you might want one of these so that you can experience those for yourself.

Basilisk II ┊ basilisk.cebix.net
⮡ A 68k Macintosh emulator; runs Mac OS 0.X thru Mac OS 7.5.

SheepShaver ┊ sheepshaver.cebix.net
⮡ A PowerPC Macintosh emulator; runs Mac OS 7.5.2 through Mac OS 9.0.4.

VirtualBox ┊ virtualbox.org
⮡ An emulator that can emulate quite a few operating systems; runs Windows NT 4.0 thru 10, DOS/Windows 3.X, and several versions of Mac OS X, among others.

QEMU ┊ qemu.org
⮡ Another emulator that can emulate lots of operating systems, with a focus on running them "FAST!"

VOGONS ┊ vogons.org
⮡ Very Old Games On New Systems, a forum centered around emulating old DOS/Windows/Macintosh games.

Old Software

The Internet Archive Software Collection ┊ archive.org/details/software
⮡ The Internet Archive's software collection is home to more than 500,000 archived pieces of software, and no doubt a thing you're already familiar with. Regardless, I wanted to include it for its sheer importance.

Macintosh Garden ┊ macintoshgarden.org
⮡ An abandonware archive dedicated to Macintosh software in particular. Contrary to what's most popular on their front page, they have much more than just games!

Macintosh Repository ┊ macintoshrepository.org
⮡ Another abandonware archive, Macintosh Repository similar to Macintosh Garden, but has some extras like its own chatroom and a list of old Macintosh computer specifications.

Remember eWorld ┊ remember-eworld.de
⮡ There's not actually software to download here (eWorld can be found on other websites anyway), but this cool website is dedicated to Apple eWorld, Apple's old CompuServe-like online service. It even has an interactive Flash replica of System 7 and several other old Macintosh programs.

Old Firmware, Hardware

EveryMac.com ┊ everymac.com
⮡ A website that lists the specs and prices of (as well as other information about) almost every Apple product you could ever think of.

GeoCities Selects

While I highly recommend perusing the Geocities archives for yourself, I understand wanting to get to the good stuff quickly.
Here are my personal favorite finds, sorted by neighborhood.

TelevisionCity

Virtual Bay City ┊ /televisioncity/1078
⮡ A cool interactive virtual version of Bay City, the fictional city from the soap opera Another World. You can enjoy it even if you've never seen said soap opera (like me).

Polar_Ice's Home Page ┊ /televisioncity/1097
⮡ An entertaining homepage. I find it hard to describe.

SiliconValley

A Page for Chinese ┊ /siliconvalley/1250
⮡ A huge collection of links related to Chinese language and resources. Also where I first saw the gray man icon that is now my "mascot."

HackUser ┊ /siliconvalley/1260
⮡ Lots of downloadable fun for classic Mac OS; emulators, viruses, phreaking utilites, etc. (Despite listing a PC section, it seems that it never came to be.)

mIRC ┊ /siliconvalley/1744
⮡ A Spanish-language page about mIRC with a perfectly GeoCities aesthetic.

rose.gif ┊ /siliconvalley/1781
⮡ All that remained of this page was a GIF of a rose on the ground, which I found both poetic and situationally ironic.

Hackman's Realm ┊ /siliconvalley/2072
⮡ A page heavier in text than images, the most interesting part of which is a downloadable preview demo of "the BOTS prologue." You can still play it on Windows 10! ("It's definitely a demo" is all I'll say.)

Stan Lee's Salsa Page ┊ /siliconvalley/2144
⮡ A page about salsa, including a salsa recipe, some salsa tips, and some salsa-related links. I have yet to make the recipe, but I'll update this entry to let you know how it tastes when I do.

Franz Glaser Austria private, Pascal, Delphi, arts ┊ /siliconvalley/2926
⮡ An Austrian page with some Austrian links, by a guy who wrote some books. I'm still not sure what it's all about, but it does look cool. This one was updated until the very end (October 2009).

Mac Man! ┊ /siliconvalley/3316
⮡ The short-but-sweet website of a dedicated Mac user.

The GeoSongs ┊ /siliconvalley/3390
⮡ A collection of songs about GeoCities neighborhoods, mean people online, and 9/11.

Lyndon's Homepage ┊ /siliconvalley/8158
⮡ A fun example of a personal homepage circa 199X/200X. Lyndon sounds like a hoot.

B.A.D. Graphics ┊ /siliconvalley/9448
⮡ A collection of free art and backgrounds, some of which I'm using on this very website.

HTML Color Code Chart ┊ /siliconvalley/network/2397
⮡ Exactly what it says on the tin, although I paid more attention to the wholesale glow bracelets ad at the top than the chart.

Some POV-Ray Renders ┊ /siliconvalley/network/4969
⮡ I'm not sure what this website is called since I couldn't find their index.html, but it seems to be a collection of (delightfully dated) POV-Ray renders.

TimesSquare

/timessquare/1322 ┊ /timessquare/1322
⮡ I can't really read this one because it's all in Chinese, but it looks to be about video game consoles, and is also an excellent demonstration of an HTML frame-sidebar.

SouthBeach

Backgrounds ┊ /southbeach/Pier/5503
⮡ A collection of links leading to some sites with free-to-use backgrounds. Useful!

Misc. Fun

Games, generators, and other random crap for ending those moments of pure boredom.
