This illusion is based on a portrait of Cecilia Gallerani, painted by Leonardo da Vinci in about 1490. The painting is one of only four female portraits painted by Leonardo. It is usually in The Princes Czartoryski Museum, Kraków, Poland. It will be on display in the Leonardo da Vinci: Painter at the Court of Milan exhibition in London from November 2011 to February 2012.
The full effect of an illusion can only be seen when it is moving, or you are moving round it. When you look from directly in front you will only see stripes.
The illusion could be used as a wall-hanging or as the centre of a bed cover.
