It that same spirit, we created Youfie, which is now available in the Apple App Store for your IOS device. Instead of dealing with an ephemeral limitation, I chose the anonymity as the shield to freedom and privacy. In fact with Youfie no registration is required and every picture taken is simply dropped at its location with no trace to the author. Furthermore, the author relinquishes rights to the picture as does Youfie. Basically the picture has been taken and abandon in its location for anyone to view with no knowledge of its author, and no one knowing who has viewed it. I felt that this would encourage many different use cases. Imagine taking a picture of a political situation and knowing that you won't be traced for bringing awareness. Or walking in Yellowstone park and seeing what was taken by others on the spot you are standing. Perhaps just knowing what has been captured in your neighborhood. No application capturing identities could reveal this unfiltered reality.
As simple as taking a polaroid and dropping where you took it for others to see. Now do with it as you please and no one will know who took that crazy picture of ... Try Youfie capture, abandon and explore.
