iKnow [L1 ] is a personal knowledge processor, a tool for bringing order to collections of information and for revealing relationships between pieces of information. It is designed to help you know what you know, and to see deeper into what you have.
From the site: iKnow is written entirely in tcl/tk, with additional support for graphics supplied by ImageMagick.
iDon'tKnow how to download the thing, though, there seem to be no links to the sourceforge project page.
