Wikiage

Did you know that the average article on the English Wikipedia hasn't been edited in 150 days? Wikiage gives an easily-assessable visual presence to the "staleness" of pages on Wikipedia and other Wikimedia Foundation sites (Wiktionary, Wikiquote, Wikibooks, etc.) by applying a highly realistic aging effect to the full body of each page based on the time since its last change.
