A timelapse film shot from the Organ Loft in Lincoln Cathedral during the 2015 SPARK! Engineering Festival shows the vast amount of work that went into the set-up days to prepare for the event and just how busy both public days and the schools day were (watch the video from 1 minute 40 seconds onwards to see how many people came along on the Saturday and Sunday!). It was filmed at 1 minute intervals at 30 frames per second over 6 days.
