I seem to remember reading some article a long time back about (not necessarily blind)people who claimed to be able to read ordinary printed text with their fingertips alone (by some kind of supernatural method) and that it was something that anyone could learn to do.
Does anyone know where I can find more information about this? (NB: I’m not for one moment entertaining the notion that such a thing actually works - otherwise they would have sucked Randi dry, wouldn’t they?)
