Many websites aren’t updated very often. In some cases this is merciful (eg ‘my pets/poetry/V8 engine mods’).
Today’s invention is a way to give visitors a rapid, visual indication of the freshness of online content. The elements of a webpage which had not been updated recently would be modified, on the fly, by one’s browser. At its simplest, this would involve a browser plug-in which detects stale content and greys it out, by replacing graphics and text with versions decoloured in proportion to the date of the latest change made to the page.
More spohisticated versions might auto-age faces, add noise, simulate cobwebs, apply sepia tinting and replace modern looking fonts with eg Gothic or Copperplate variants.
