Left to Right: Space Cadet, Virtual Violet, Space Cadet
In full sun, it was hard to tell that I had 2 different polishes on, but in medium light (indoors), the duochrome effect of Space Cadet really shone. It shifts from reddish-purple to a dark chartreuse, and is pretty spectacular as a polish!
Space Cadet is somewhat hard to find; it came out in fall of 2010, and isn't part of Orly's core line. Some Ultas have had the Cosmic FX collection in stock (I just found mine two weeks ago at the local Ulta), but otherwise, online is your best bet. Hard Candy has a polish called Beetle that is a dupe for Space Cadet, and you can find that color at almost any WalMart, so that may be the easier route to get this fantastic color!
