A film in eight chapters that you can stop, scrub and take apart. Every chapter has its own controls in the panel on the right.

• Play the film, or jump between chapters with the chips at the bottom. Drag the chapter timeline to scrub.
• Grab the view at any time: drag to orbit, right-drag to pan, wheel to zoom. The film camera lets go; press F or “Film camera” to hand it back.
• X-ray: in chapter 2, click anywhere on the ground to open the glass there. Toggle the hidden networks in the panel.
• Follow the bag: chapter 3 rides a suitcase. Change the ride speed, the camera mode or the bag itself.
• Turnaround: chapter 4 runs a schedule. Add a late arrival and watch the plan reshuffle.
• Panel tabs: Chapter · World (time of day, traffic) · Camera · Look (post, quality) · Vitals.
