Scan your memories of your own excursions far from home. Keep the scan active as you make a list of 20 things, a mix of objects, visual elements, sonic elements, technologies, and populated locations. Keep moving your mind through places you’ve been to, scanning the remembered scenes for image, object, sound, technology, location ripeness.
Then turn the page over and write compact overviews of each scene in a new four-scene story. Weave and pluck and freely combine from your list of 20. Let all the substance of this outline be built of recombinations derived from this inventory you’ve made.
