I think the "between your eyes" refers to Augmented and Virtual Reality devices like Google Glass, that are between your eyes. It's also interesting to note that in Hebrew, their number system is based on their letters, so the number 6 is the letter vav, which in English would be W. So 666 could be translated as WWW. It's been very frustrating to me that I've told this to so many Christians, and almost everyone seems to be sure that it is just a coincidence. But that would make sense, since John says that the "whole world will be deceived".
