The Harry Potter bandwagon continues with the familiar hype and merchandise overkill that we have all come to expect.

This screensaver accompanies the fourth adaptation of the yet-to-be finished heptalogy, where we find the lead characters of Harry, Hermione and Ron dealing with the trials and tribulations of becoming teenagers, while continuing with the task of defeating Death Eaters and evil impostors.

If reports are to be believed, this installment brings more gore and terror to the screen and an unprecedented 12A certificate. Unfortunately, the screensaver displays none of these potential qualities.

What we get is a rather drab affair, comprising a moody backdrop of Hogwart's interspersed with pictures of Harry and Co looking moody and much older than they should.

However, this will no doubt be a must for avid fans.
