Carrying around a Nokia N800 and want to organize some thoughts? Consider looking at Eugene Antimirov’s Maemo port of Labyrinth. It’s an alpha for now, so be forewarned, but he’s got this Python-based mind mapping application working on his Nokia Internet Tablet. While I prefer to do a brain dump on a larger screen, I more often have smaller-screened devices handy when I have that rare "good thought of the day", so I see the draw here.
