The folks behind the Lua programming language maintain a page detailing the release dates of all released versions of the language. My favourite thing about that page is that right at the top there is a graphical timeline, with years marked below the line and a little vertical marker above the line at the appropriate place for each release. This timeline makes it immediately obvious at a glance that Lua is doing something all software projects ought to aspire to but very few actually manage to achieve: it is slowing down.
