  Changes: the ship's name, hull markings and the container operators' logos wiped with a median filter so that
  no lettering is readable; cut out, colour graded; also shown uncut (lettering wiped) as a pinned print.
- Beam bridge (kit object "beam")

  https://commons.wikimedia.org/wiki/File:Fort_Henry_Bridge)_Wheeling,_West_Virginia_LCCN2015632042.tif
  Changes: cut out; a road sign under the arch removed; hangers lost against the hills continued down to the deck
  at their measured positions.
- Cable-stayed bridge (kit objects "cable", "print_cable")
  "East Huntington bridge, Huntington, West Virginia" by Carol M. Highsmith, Library of Congress, public domain (PD-Highsmith)
  https://commons.wikimedia.org/wiki/File:East_Huntington_bridge,_Huntington,_West_Virginia_LCCN2015631874.tif
  Changes: cut out; a water-level gauge and a road sign painted out; the stay cables measured in the photo and
  redrawn as clean lines; the single pylon with its main-span fan mirrored to make a two-pylon main span
  (a composite that represents the bridge type, not a real bridge).
- Suspension bridge (kit objects "suspension", "print_susp")
  "Bear mountain bridge west II" by Russ, CC BY 2.0 (https://creativecommons.org/licenses/by/2.0/)
  https://commons.wikimedia.org/wiki/File:Bear_mountain_bridge_west_II_(14104379089).jpg
  Changes: cut out, desaturated; the main span between the towers stretched horizontally (×1.7) so the
  towers keep their shape at a two-kilometre span; the main cables (fitted parabolas) and the hangers
  (measured positions) redrawn as clean lines (represents the bridge type, not a real bridge).
The four "print_*" objects are the same photographs, uncropped, on a white photo-paper border, pinned at the
top right of the wall. No real bridge, ship, company or place is named or readable in the film. The licence
trail of every photo looked at is in sources/candidates/candidates.json; kit/tools/fetch_sources.py downloads
the six used ones from Commons.

The whiteboard, its light and ghosts, the frame and tray, magnets, tags, the steel ruler, the cards and sticky
notes, the clearance sketch, the rubber stamp and all marker ink are drawn in code.
