A while ago I helped my friend Patrick make a portrait of himself on the sandyish beach in Hove.
We used dried sea weed for his hair, pebbles for his eyes and starfish for his mouth.
It was part of his application to do Architecture at Cooper Union in New York (the second hardest college to get into in the US after Harvard). HE GOT IN, which is not surprising really if you look at the work on his blog!...... http://patrickcollingwood.blogspot.co.uk/
