This is just some fun stuff that doesn't warrant a top level shortcut!

neal.fun- A wacky lil site with tons of toys and gizmos, I've been here a few times and they always seem to add something new
vole.wtf- A site with really fun design and random concepts, I can see myself playing with things on here for a few hours :P
thehtml.review/01 and thehtml.review/02- "The html review is an annual journal of literature made to exist on the web"
24hourhomepage.com- The 24 hour homepage will have an image and an associated link appear every second of every day.
EmuOS- This one is kinda weird, but don't knock it until you've tried Pikachu Volleyball! [Malwarelessness is NOT guranteed]
Windows 93- My favorite version of windows that Bill Gates DOESN'T WANT YOU TO KNOW ABOUT
dashnet- 🍪
explorabl.es- explorabl.es AKA Explorable Explanations has a seemingly endless myriad of interactive and educational internet gizmos and thingamajigs.
Vectorpark- Vectorpark is pretty infamous, in my mind, for their strange flash "experiences" that plagued my early web browsing days. They've mostly been preserved and are available here.
