So, how have I created this image?
Step 1. Make sure you have a sturdy tripod.
Step 2. Make sure you have a compact flash light in your hand.
Step 3. Set your camera on  30 sec exposure.
Step 4. Walk along the rocks freezing for 5 seconds with every step. Move the torch only as you take each step.
Step 5. Repeat this about 20 times and play with the aperture setting until you like what you see.

I'm a huge fan of light painting and am having a lot of fun learning more and more about it.

Have any questions about 'tricks of the trade? I might be able to help.
