Today marks the first birthday of [script.aculo.us](http://script.aculo.us), which was launched on [June 22, 2005](http://mir.aculo.us/2005/06/22/script-aculo-us-launched/).

Since it’s humble beginnings as an [effects add-on to Prototype](http://mir.aculo.us/2005/04/10/effects-for-ruby-on-rails-apps/) and coming directly out of what we at wollzelle needed for [fluxiom](http://www.fluxiom.com/), it’s seen many uses on [high-](http://www.apple.com/aperture/) and not-so-high-level web sites, plus it’s covered in many articles all over the web and the blogosphere and all [kinds](http://pragprog.com/book/rails2/agile-web-development-with-rails) [of](http://pragprog.com/book/ajax/pragmatic-ajax) [books](http://shop.oreilly.com/product/9780596101695.do).

Conservative estimates are that script.aculo.us has had **more than a million downloads** (counting the packages from the [script.aculo.us download site](http://script.aculo.us/downloads), and the inclusions within frameworks, first and foremost [Ruby on Rails](http://rubyonrails.org/)).

script.aculo.us was an enormous success (it ranks #4 in the del.icio.us all-time popular sites!) and personally I’m very proud of it (and all the people that contributed to it!).

A big thanks at all the contributors— let’s see if we can make the second year as exciting as the first.

The Web is **still** changing.
