Thanks everyone for the ideas! I will try the car in dark garage thing once I get the chance.
Here's the photo I was referring to.
Did the shooter use an external lighting source? Or were the effects created by some sort of flash?
I have another question that may be a little off topic here: Do I have to use the ring flash for macro photography? I just got a normal flash (Olympus FL 36) and I can't seem to point the flash directly to the object right in front of the lens.
