With this application, you can make a wonderful picture easily. The picture you made includes your messages inside. You can only see the messages, if you see the picture through the direction of the charge mouth of iPhone. This is not real cipher. But it's hard to read. Can you read THIS??? FYI, if you can't see the messages well, please watch this movie I made. http://youtu.be/xkblFaH-PXQ This is Japanese version. But you can find how to see the picture soon.
