Many of the Luminata attendees had decorated lanterns on pole. In this video they are using the lanterns to interact with the waterfall.
At Luminata, a clarinetist sat down against a tree and began improvising based on participants’ movements. The resulting collaboration was spontaneous and hilarious. Credit to Mr Ed Sullivan providing the music.
Viewing the back side of the installation is interesting because you observe the ghost-like effect of the performer/participant without seeing their actual person.
