Vulcan salute

The Vulcan salute is a hand gesture which became popular by the 1960s television series . It is done when the hand is raised with the palm forward and the thumb extended, while the fingers are parted between the middle and ring finger. It is a symbol of greeting by the character Spock. Nimoy based it on a hand gesture used by Jewish priests called Kohanim to bless people in Orthodox Jewish synagogues.
