Interactive Book Cover

The old adage is "you can't judge a book by it's cover" but maybe you can.  As I was browsing book blogs last night I came across a Young Adult fiction, Daylight Savings by Edward Hogan  The book sounds interesting and I do enjoy time travel novels, but I was especially attracted to the cover.  The design flows as if it was liquid when you move your cursor across it.  Whether you choose to read the book or not I recommend checking out the cover.  Amazing!
