"For the laser geeks out there, 100 power / 60% speed (on a 35W CO2 laser)."
And, for all you "covenentally-challenged" readers out there, here's another load for your storehouse of useless knowledge (Jews already know this, genetically):
In his autobiography I Am Not Spock, Nimoy wrote that he based it on the Priestly Blessing performed by Jewish Kohanim with both hands, thumb to thumb in this same position, representing the Hebrew letter Shin (ש), which has three upward strokes similar to the position of the thumb and fingers in the salute. The letter Shin here stands for Shaddai, meaning "Almighty (God)", and has a special significance in Judaism. Nimoy wrote that when he was a child, his grandfather took him to an Orthodox synagogue. There he saw the blessing performed, and was very impressed by it.
"The accompanying spoken blessing, Live long and prosper... is similar to the Hebrew greeting, "Shalom aleichem" (peace be upon you) and its reply, "Aleichem shalom" (upon you be peace)."
