The limited edition game has taken an unexpected turn. This time it's the wind-harnessing maestros at Dyson that have stepped in on the action, introducing two new sculptures of engineering - the DC24 and DC25 'Drawing' vacuum cleaners.

The sleek machines - featuring Dyson BallTM technology - are annotated with notes that honour the methodical, step-by-step design processes of the great heroes of invention, like Thomas Edison and Richard Buckminster Fuller, while their boxes pose a number of engineering challenges. You can test your creativity by building a spaghetti bridge inspired by Brunel, or a geodesic dome from cocktail sticks. Thanks to Dyson, doing the vacuuming will never be a chore again.
