The video shows how Kevin is constructed out of a simple half circle, and then quickly moves on to the team daring Philip and me to make pictures from other shapes.

The website comments are open if anyone else wants to take part. You can make it a game for yourself or to play with a friend, making up drawings from shapes. Then use those shapes in a story!
Here we are with Blue Peter editor Helen Varley and her camera crew. Oh, and you can learn how to draw Kevin step-by-step on my website!
