Someone (I think TicMan?) mentioned TiddlyWiki a while back; its a cool simple personal wiki you can use for note taking. I've been using it on and off since; it's really handy.

Was reading this post on the Google Open Source blog and it mentioned a new thing by the dude that made Tiddly called Project Cecily which is like TiddlyWiki with a cool zooming UI thing.

(NOTE you'll have to be using Safari or a new WebKit build or Firefox 3.1 Alpha to be able to use it. )

It's pretty neat; not sure if it will be really usable but a cool concept.

Oh god.. it hurt my head with all that zooming.

Thats pretty sweet...
