Google Earth has come in for some stick over time.

Its Street Map was launched amid a healthy bout of controversy over privacy. After one man was identified leaving a brothel, resulting, unsurprisingly, in the end of his marriage, Germany wisely opted to make sure coverage of properties was somewhat blurred. Meanwhile, enterprising bloggers have posted pictures of prostitutes plying their trade, drunks and nudity.

But while that may be one window to the world, Google Earth also offers another. For a guy who once spent a week on an archaeological dig getting sunburnt while recovering the remains of someone’s mediaeval camp fire, Google Earth’s option to slide back into vintage photos of the same aerial view is a guaranteed way for me to fritter away hours.

You’ll need to have Google Earth 5 downloaded to do it, but it’s free and well worth a nose.
