Attendees at the 2017 Tableau Conference were invited to participate in a scavanger hunt.
Construct, by hand, a limited run of paint-by-numbers coloring books, using impactful data visualizations, for the hunt.
Coloring books were hidden throughout the conference center. Periodically during the conference photos of them, at their locations, were posted via Twitter along with a few guiding words to help participents find them.
