I really find myself trying to figure out what this is. On the one hand, that's fun as I kind of get to make up what the object is. On the other hand, I feel lost and confused.
Obvious tripod use: Medium. It's really hard to tell if the object is moving or if the camera is moving.
What a wonderful crazy image. Your eyes can wander all over it and see so many interesting shapes. However it is not obvious to me that this could not be handheld, as there are no clues at all to the subject or technique used.
Obvious use of a tripod, or any other long-term stabilization tool (1-10 *is not the score of the shot though*): 3
Without knowing what I'm looking at, it's very hard to tell if this is something that required a tripod to accomplish.
