This is pretty rad. I especially love the scanlines on VECTRO. I saw there was supposed to be an animation on it, but it was commented out so I forked it a little and started tinkering. Here's my attempt at CRT nostalgia:
Actually your site works just fine without javascript once I get rid of that annoying 'this site does not work without javascript' message.
Edit: the site. Honestly I meant 'your' as in the site owner. I'm just annoyed by sites that block their content that loaded just fine because I'm not running javascript.
This little CSS experiment is usually the kind of irrelevant demonstration that is commonly frowned upon because it has no practical use.
But no matter how apparently futile this showcase can appear, it's still inherently valid because it maintains a clean separation between content (which in this case comprises 14 lines of HTML) and its representation (provided by its CSS styling).
Build anything and someone (usually the top comment on Hacker News) will dismiss it, mock you for wasting your time, and talk about how X was already solved years ago.
See also: the engineering dance. When two engineers meet and shit test each other on their knowledge, until both are satisfied they are better than the other guy.
I'm getting similarly horrible performance on Chromium what-I-assume-is-latest (32.0.1700.107) on Arch Linux; Firefox has no performance issues but doesn't actually render all of the CSS being showcased.
80s typography is probably best exemplified by Neville Brody. Process colors were rarely used (owing to expense) so it tended to rely on a lot of very dramatic and grungy layouts and spot colors.
