I think I'm having Designer Series withdrawal. Every time I go a while without wearing a DS polish, I start going a little nutty :-P
OPI Designer Series Glow
This is one of the newer DS polishes -- it was released recently along with a darker, almost-black DS polish called Mystery (coming up at a later date!). Glow is a gorgeous burnt gold/copper color. It is not as holographic as the other Designer Series polishes, and it was a tad thin and runny during application, but after the coats built up enough, the gorgeous and unique color started to come through, and I was won over. It is truly unique among all the DSes. I don't think there's another one that comes close to this color family.
