A favicon wall is a design competition whether it means to be or not, and this district wins it. Design tools, type foundries, icon libraries, illustration marketplaces and the creative software around them all live here, and their icons are the ones visitors zoom in on.
Every square is 1×1 and the favicon is fetched from the site itself, so what you see at 64 pixels is what the site ships in its own tab. A few of the sites below look better here than on their own homepage. Sort by kisses to find them.
If yours is here and you would rather it showed a different icon, the town re-reads a site's favicon on request from the square's card, and an admin can pin one of the alternatives a site publishes.
