paint with light

I was playing with a 30sec photo and sketching away with a torch light. Well, I came across the amazing artist, Goro's light paintings http://www.area-56.de/chapter56/labels/Light%20Paintings.html and thought you guys could take a look at it. His work is amazing! I hope to get in touch with him and see if I can add him to my list of Friends/Inspirations!
