The app, PolyFauna, is a collaboration between the band and Universal Everything-a UK-based digital art studio-that allows fans to use the imagery and the sounds from the song "Bloom" to enter an "evolving world."

"It comes from an interest in early computer life-experiments and the imagined creatures of our subconscious," Thom Yorke explained of the project, which was born from the King of Limb sessions, via the band's website.
