I find the concept of "photographic", e.g. Eidetic, memory fascinating. Mainly because its so specific. Why only the visual sense? Do people exist with perfect recall of taste or hearing or touch or smell? Is there a show in development called "The Smentalist"? I find this very odd.
What's more, I find it odd that the wikipedia entry on Eidetic Memory is so sparse. For an ability that seems to be so amazing, the entry seems rather underwhelming, possibly to the point of never having existed.
Part of me wants the ability to exist. And part of me wants the ability to manifest itself through the other senses. How awesome would it be to recall the best burger you ever had with perfect clarity? The perfect kiss? The perfect song? The perfect fart?
