The Victoria & Albert Museum in London is to display work by the art, science and engineering genius Leonardo da Vinci.
The museum promises some of da Vinci's "most complex and challenging designs" when the exhibition opens on Thursday.
The V&A says: "The intensity, variety and unpredictability of what happens on a single sheet are unparalleled."
The exhibition's four themes will include The Mind's Eye, exploring the relationship between the eye and the brain.
The gallery has gathered 60 drawings from British collections, which are being brought together for the first time.
Da Vinci's scientific achievements are ranked alongside his artistic masterpieces such as the Mona Lisa.
Huge models of some of da Vinci's designs will be on display - including his flying machine, tank and giant crossbow.
Some of the drawings will be brought to life with computer animations. The exhibition runs until 7 January 2007.
