The wet weather failed to put off plans to project a giant image of Queen Elizabeth II, made up of 200,000 self-portraits by schoolchildren, onto Buckingham palace.
The Face Britain project was created by Prince Charles' Foundation for Children and the Arts.
The images are also being broadcast for 24-hours on big screens in 18 public locations around the country.
