Fractals is good to use for Changing Worlds, because it's a comment on two levels;
1.)The relatively recent discovery of fractals (1970's?)
2.)The medium of presentation, the multimedia encyclopedia is deliberate, to represent changing ways of presenting information, with interactivity and other features..
Unfortunately, that doesn't relate for 'Changing Self'. I'd like to use Sturt's Dreaming, but that doesn't work for many questions in this area, so I'll probably be using 'Sky High'.
