Back in the not-quite-as-bad-old-days (at least as far back as the 90's), every good website had a small "ad" gif that fans of the site could use as a colorful link. These are called "buttons" or sometimes "pins."
You can see sites that collect these internet artifacts (both the good ones and boring ones) here and here.
Most people would have dozens of these at the bottom of their site, linking to all their favorite sites, back when people actually linked to things because search engines hadn't taken over the internet.
The only rules are:
- It has to be 88 by 31 pixels.
- It has to be a .gif.
- And it should be animated, colorful or memorable (but some people do the gray ones to be ironic or boring).
Since we're all trying to Reject the Modernity of the current internet, I figure I should do my part to bring these back.
I made a little button for LARBS, which you can see here:
Nice, simple, noticeable and memorable. Best of all, at 88x31, it's very small. Adding dozens of these to your site is a great way to link creatively without using more than 90's bandwidth. After I get a good collection of them, I might link my favorite sites with them.
So I encourage you to make some of these for sites you like. You're even welcome to make some for my sites: LandChad.net, Not Related, heck, even Based.Cooking, or even my personal website for that matter.
I might talk about these things in a video later because it's one of those aethetical niceities that has been lost to time.
(PS: GIMP can make gifs, look it up, and remember to "Optimize for gifs" after you're almost done to make the filesize super low.)
