@zoem: Target, something like fifteen bucks. It's tension with supporting brackets, and yes, I found that on this model you do need the supporting brackets and tension won't hold it alone.
@Harlotbug3: No, the damn things are gestating inside the camera itself. We're training them to attack when the aperture and ISO settings are at a specific combination, launching themselves at the object in focus.
@MagicSword!: that's what I was hoping for...mine got one eye drawn in 2005 and it's still waiting for the second eye......but this might be a good year
