Atoms for Peace are all about the fun and games. A secret track has been discovered on the band's official website, hidden inside the sprawling black-and-white collage designed by longtime Radiohead artist Stanley Donwood that's featured on the front page. To download the tune, 'What the Eyeballs Did,' for free, scroll all the way to the right of the collage and click on the face of the clock tower furthest to the right.

'What The Eyeballs Did' is the B-side of the 12-inch vinyl record for ‘Default,' the first single off the band's forthcoming debut album, 'AMOK.' Atoms for Peace were previously streaming the track for free, but they've since taken it down -- only to post it again in this more mysterious manner. 'AMOK' is due out Feb. 25 in Britain and a day later here in the States.
