Eurostar's Art Gallery

Eurostar has launched an interactive art gallery in the departure lounge of its London terminal St Pancras International, in conjunction with the National Gallery. Chunnel travellers can choose from 100 paintings, such as Hans Holbein's masterpiece The Ambassadors (1533), using touch screens on coffee tables. Did you know that if you stand to the side of this painting the "French stick" on the carpet becomes a skull, Holbein's reminder that even the great and the good dressed in their finery are mortal? I'm not sure whether this clever visual illusion works when viewed on a plasma screen. Let me know.
