The Coolight is from designer Wen-haur Yen, otherwise known as the modern day Einstein. It's essentially a battery powered rod thermometer that fits in a bottle. Encapsulated cryogen keeps your drink cold (and will double to put your sober personality in stasis). LED colors can denote temperature, time...the real world possibilities are endless.

Green: You are a nice person with whom people enjoy socializing.
Yellow: You are a funny person with whom people enjoy socializing. Maybe you are good at dancing, too.
Orange: Abort mission! That drunk you are necking will be ugly in the morning/under a light source of 40W or greater.
Red: You shouldn't have brought the bottle home alone. Why doesn't she love you? You are an asshole; nobody likes you. No, not even your cat, he just needs sustenance and often contemplates eating you in your sleep. Don't drunk dial. Too late. Pass out.
