TiddlyWiki

TiddlyWiki (http://tiddlywiki.com/) is written in HTML, CSS and JavaScript.

It has interesting interface features:

clicking on a link don't let you leave the page, but inserts the topic text in the current page, in a kind of BookView way. This way the page becomes blog like.
when a topic text is inserted, the page scrolls with it, and a "insert" rectangle animation is shown
action buttons appear on mouse over each block
backlinks ("references") uses search word colorizing
clean history list (column) organized by day

There are several TiddlyWiki adaptations. The nicest by far is GTDTiddlyWiki ( a getting things done wiki).

And if that isn't enough, get this: if you save the web page to your hard drive, you've saved the whole application. There is no server-side program. (Ponder that for a moment.)

Yeah, TiddlyWiki is pretty cool allright. I'm watching that project with interest. If you like the idea of an all-in-one-file wiki look at the MetaKit based Wikit which has been doing this for years.

the Zope based server-side implementation http://timmorgan.org/ZiddlyWiki/ also allows ex- and importing the tiddlyWiki for on/offline working
