We've made it! Another year, another Advent Calendar over. We hope you have enjoyed the pictures, stories and videos and have a wonderful Christmas yourself. This year we have a competition (NOW CLOSED) to win a very special Christmas tree surprise! All you have to do is work out what colour shirt Adam is wearing in the picture below. The catch is it was taken at the National Gallery 'Monochrome' exhibition in a room containing only yellow light ! With a merry Christmas from both of us!
