Far be it from me to encourage web-surfing on a slow, hungover Friday... but if you're so inclined, head on over to <a href="http://www.opi.com/" target="_blank">opi.com</a> to play with a fun new feature that allows you to "virtually" try on more than 200 shades of nail polish. The tool allows you to customize for skin tone, and most importantly, nail length. Because we all know that long, dark nails DO NOT look good. Right?
