Thanks guys.
Yeah, I cloned some spots and such and then got lazy about the "V" because it's pretty light, but I will go back and remove it. BTW, it's not sensor dirt because it's not in any shot I've taken with that camera before or since. Like the stuff I cloned out it must be a scratch (in focus) on the plastic panel on which this pattern was projected (early AM sun through a glass block wall, I think).
