PolyFauna is an audiovisual trip through the sounds and imagery of the band's music.
Radiohead developed the game in collaboration with mobile developer Universal Everything. "It comes from an interest in early computer life-experiments and the imagined creatures of our subconscious," the game's App Store description says.
"Your screen is the window into an evolving world," it continues. "Move around to look around. You can follow the red dot. You can wear headphones. You can get some pretty strange looks on the train," it says.
If you're a Radiohead fan or just into experimental apps then it sounds like PolyFauna might be worth checking out.
