Picked up a few shadows from MAC's Surf Baby collection and I have to say, they're SO gorgeous. I don't have anything like them and they're all crazy pigmented. I didn't pick up the grey eyeshadow though...kinda wish I did!
My favorites are Surf USA and Sun Blonde, and Sun Blonde is likely the most unique. It's a dirty yellow...totally different from any yellow I own. If you love yellow shadows, I highly suggest Sun Blonde!
