These enormous 3D pavement sketchings are made by Julian Beever, internationally renowned artist, often called the 'Pavement Picasso'.

Julian has made pavement drawings for over ten years. He has worked in the U.K., Belgium, France, The Netherlands, Germany, the USA and Australia.

An anamorphosis is a deformed image that appears in its true shape when viewed in some "unconventional" way. However anamorphic pictures are stretched, so that while they look fine from one particular viewpoint, they look quite strange and often unrecognisable from any other viewpoint.

From one position - where the picture above has been taken from - everything looks normal. Except that the pool isn't really there, of course - Julian's foot is touching the pavement, not the water!

This shows the same picture, but this time seen from the other side. Now the girl's leg looks extraordinary, elongated and distorted. Only from the other side, when a large amount of fore-shortening takes place, does her leg look correct.

Here we see the same Make Poverty History drawing from the side : it was 13m (40 feet) long.

Julian works in chalk, so his art, which takes up to 3 days to complete, last 'till the first rain.

People are actually avoiding walking in the "hole".
