Search giant Google is marking the 80th anniversary of the film 'The Wizard of Oz' with an out-of-this-world webpage.

The company is paying homage to the film's creative achievements in Technicolor, and the telling of the story.

The 1939 film follows Dorothy (played by Judy Garland) and her dog Toto, who are are whisked away in a tornado to the magical land of Oz.

They follow the Yellow Brick Road toward the Emerald City to find the Wizard, and meet a Scarecrow, Tin Man and a Cowardly Lion along the way.

If Google users search for 'Wizard of Oz', a small icon of the famous ruby slippers appears in the right-hand corner of the screen.

Click on these, and the user is taken back to Kansas (so to speak), as the screen rotates several times and turns black and white.

The lines 'There's no place like home' are also heard.

The page remains fully scrollable and interactive in the greyscale format.

Users may notice that the ruby slipper icon has now become a moving tornado, which will transport you back to Oz.

Dorothy's house then flies out on the screen, which rotates again and returns back to colour.

Soundtrack from the film is also heard, with Dorothy calling for her 'Auntie Em'.

According to Google Trends, Ireland comes in at number five in a list of countries with the highest search interest in 'The Wizard of Oz' since 2004.
