图片新闻【511】革命性的小闹钟

A 25-year-old Massachusetts Institute of Technology student has invented a revolutionary alarm clock 'clocky,' in this undated photo, that falls to the floor and rolls away on the first push of the snooze button. To turn it off, a person must get out of bed and find it. The clock features two rubber wheels and is covered in thick, 1970s-style shag carpet and other material to cushion it when it tumbles to the floor.
