The Mind Massaging Machine is a program that plays binaural audio, spirals, strobe lights, etc on VR headsets. Never tried it myself, but it seems like it should allow you to use preexisting files with it.
articlehot said: There was once a blind man who had so fine a sense of touch that, when any animal was put into his hands, he could tell what it was merely by the feel of it. One day the cub of a wolf was put into his hands, and he was asked what it was. He felt it for some time, and then said, "Indeed, I am not sure whether it is a wolf's cub or a fox's: but this I know -- it would never do to trust it in a sheepfold." Evil tendencies are early shown.
