Loremipsumdolorsitamet.com is no longer online. At least not in it’s proper form. However, you can view a copy right here. As the page says upon clicking the [info...] link, “Purely coded in JavaScript. This means you can save this page locally (File → Save As…) for offline use.” Or, online use in a different place.
So, what is it? A filler text generator with a choice of Lorem Ipsum, English, Jabberwock, or Tagalog. Enjoy. Especially if you miss it.
Update: Here is the official new location, I think. Complete with background image and header (yum yum). It seems to have originally been designed by Rico Sta. Cruz. The source code refers to his old site, ambiescent.com. His new site is ricostacruz.com, and Lorem Ipsum is now hosted at a subdomain there.
