Thames Gigapixel Puzzle

Thames Gigapixel Puzzle

A giga-pixel puzzle for the launch of a Stephen King book.

To promote the release of Stephen King’s novel Under The Dome, the final 2 sentences were exploded into paired words and hidden in a gigapixel photo (a large, composite image) of London City, beneath St. Paul’s dome. The words were not super-imposed graphically, but were instead held by volunteers positioned around the Thames north bank. Fans of the fiction writer were challenged to decode the sentences with the chance to win a pre-released copy of the book.

We played a consulting and creative logistics role in the activity, making sure everything came together on the day. The gigapan camera was positioned on a viewing platform at the Tate Modern. The diagram below shows how point sizes were calculated, so they would appear equally sized from that position.
