Hi Eve! :)
I'm on steemit since...yesterday ( :D ) but I'm trying to do my best to post and find useful, entertaining content!
So, regarding your idea, have you ever tought to use a wearable that, for example, take a random photo every let's say five minutes and then select from those photos a "selfie" that really represent you in your real life?
I ask this because I find that even the fastest, most casual and less refined selfie, at the end, results in a sort of unnatural look.
After all, our brain easily spot the camera and act like we are in front of a vast group of people. With an automatic, random selfie device maybe this would be avoided!
