Who is a Christian pastel artist who draws live in front of an audience?

When I was young my school would often have an artist come in and draw beautiful religious scenes live in pastel with colored lights shining on the canvas for dramatic effect. Although I'm not religious I still have an appreciate for the art. It was very beautiful to see how he formed the scenes in those beautiful vibrant colors. I'm wondering if anyone knows of an artist in particular who performs like this.
