@bbcmicrobot The idea that The Great Wave is fractal goes back to Mandelbrot himself, tho I've not seen an attempt to render it with fractals? I tweaked the editor to have a background image to help with choosing the parameters.
@bbcmicrobot in case anyone wants to do similar tracery: I used the developer console to add this to the div with id "emulator". You'll want to tweak the size for whatever image you're using. <img style="position:absolute; width:778px;z-index:1;height:622px;opacity:.2;" src="https://upload.wikimedia.org/wikipedia/commons/thumb/a/a5/Tsunami_by_hokusai_19th_century.jpg/1920px-Tsunami_by_hokusai_19th_century.jpg">
@bbcmicrobot @bazzargh Very cool IFS!
@bbcmicrobot @bazzargh I converted the code to #applesoft BASIC and ran it in KEGS an #appleii GS emulator. https://mmphosis.netlify.app/hires/greatwave/
