This picture has been my laptop wallpaper for the last many years as I worked on Channel Zilch:
I am touching a space-flown Space Shuttle wheel on a shuttle replica at The Cape. I made sure that in Channel Zilch the protagonist, Mick Oolfson, touches the tire of Shuttle Enterprise when he first sees it.
That picture worked its charm and now I can retire it because I’ve finished Channel Zilch. It’s on to Castle Rising, my medieval-kids-vs.-alien-armada book, so I changed my wallpaper to inspire me with views of the homes of the four protagonists:
Upper left is Castle Rising in Norfolk, England, the home of Will the apprentice scribe. Lower left is Angkor Wat, home of Visel the reluctant martial art student. Lower Right is the Far View Site at Mesa Verde in Colorado, home of Avis the hunter. Upper right is the Hill Complex of the castles of Great Zimbabwe, Zimbabwe, home of Shenkasi the prince.
Now to write Castle Rising!
