Space Odyssey was offered during the recent New York Fashion Night Out event. It is also the Holiday 2011 nail polish offering along with Endless Night. I was lucky enough to find both on Ebay about two months ago. I bought them knowing nothing about them except that they were cheap and I didn't own them. *sniff* I love a happy ending.
Space Odyssey is a shimmery silver foil. Lovely but not unique. A wee bit let down that this is what Nars decided to put out for a holiday color. I would love to see Outremer (the eye shadow) as a nail polish. I think that would be stunning!
