Pixelknot: Steganography app for Android

Steganography is an old concept, so Pixelknot is not a ground-breaking application, but this is how it works. Say you wish to send a short, text message to a friend and you do not want an unauthorized person to see it. You take a picture with your smartphone, or use an existing image, type the message you wish to send, let Pixelknot work its image, then send the image on its way.
