People criticize fancy lingerie saying, "Oh, you spend all that money on underwear and then no one--maybe one person--sees it." The common response to that is, "Yes, but it's not for other people, it's for yourself." But what about when you're wearing fancy lingerie and you're wearing a super fancy blindfold as well?
Again, we think the common response is the right one. You're not wearing it for your eyeballs, you're wearing it for the feeling, for the strange feeling of a room full of air that appears whenever you can't see, and for the way the solitude makes you unusually aware of everything that touches your skin! Elena Melnik is exactly where she needs to be: alone, mostly naked, mostly blind, and mostly in front of a camera.
(They mostly come out at night, mostly.)
