A lot of people’s personal sites are still like this. The trend never really bucked for that.

Although it’s more the websites for designers and artists rather than developers.

There are also websites that showcase these types of websites, although I don’t know any anymore.

I have to say, building these kind of websites is more fun now in HTML than Flash because you aren’t constrained to a fixed viewport. And HTML has surpassed in Flash in features and you have WebGL and WebAssembly and other fun things… well, except a nice IDE with a timeline.
