From Wikipedia – TiddlyWiki:
TiddlyWiki is a wiki-modeled
client-side single-page application
Does anyone know of anything else like TiddlyWiki? It seems to stand alone in its field.
Specifically, it is a self contained single file that modifies its own content. Besides a web browser nothing else needed to change the page(s) content. It can be accessed via file:/// without a server and change the content.

Wiki on a Stick is a similar concept to TiddlyWiki, but laid out slightly different (more traditional Wiki style than the "micro content" approach of TiddlyWiki). It works well, just a single self-contained, self-modifying HTML file just like TW.
