2. What do you need? A tri-pod (Don’t have one? No problem!)
Dark room or lack of light
A torch (flashlight)
A very low shutter speed
This was not done with a camera

3. Step 1: Set-up
Set your camera on the tripod and take a sample shot with flash / lights on. This will help you verify that your composition is OK.
Set the exposure to a relatively long value. Stop down the aperture as much as you need. If you are outside do nothing. If you are inside - this is the time to turn off the lights.

4. Step 2: Taking the shot
Make the click. Once the shutter is open use your flashlight to light the stuff that you want to "paint". You can use the flashlight as a brash, and "smear" the light, just like you would have done with brush and paper.

5. Product like shot
In a closed (dark) room place your product on a table and paint it's contour. You can use several colors to make a strong effect or to draw different (even imaginary) parts of your object.

6. Location shot
Find a location with some ambient light. Find an object that is less "hit" by that light. Now you can use the ambient light to capture the background, while painting the object with light. You will get a nice effect - with some surreal foreground and a "normal" background. Also the white balance will be different on ambient and painted - another cool side affect.

7. Environmental Graffiti
If you are shooting a wall (or even on thin air...), you can scribe on the wall. Make funny graffiti; Write huge love notes; Make a political statement - there will be no trace left other then the one on your memory card.
