Earlier this year, Radiohead released a rather beautiful looking app called PolyFauna (inspired by their 2011 album The King of Limbs) - which was basically the budget version of Björk's Biophilia app. At the time it caused quite a fuss, but let's be honest: when was the last time you PolyFauned? A month? Two months? That might be about to change...

The band have decided to give the app a major makeover, uploading new visuals and sounds - which is very exciting since the term "unreleased" has been thrown around.

Could this by the start of a long, boring press campaign? Probably not, but you never know.
