The third and what turned out to be the final event was Lightwalk in 2004. This was held over several nights at Indiwell. I'll see if I can find some Photos of that event.
Unfortunately due to Foot and Mouth in the country the fourth event in 2007, to have been held at The Valley of The Rocks, was postponed, unfortunately Dave Bryant passed away before it could be re-scheuled. I have no information or photos of the preparations or theme of this one.
