A new iPhone App produced by PKD is now on sale. The name is PKD Flag Signaling. You can learn Japanese style flag signaling by using this App. It’s really easy to learn for Japanese because it is based on KATAKANA, a Japanese simplified character. I guess, you can learn it in one or two hours with this App.

Flag signaling is a primitive long distance communication way. With this App you can learn one of the oldest way of long distance communication by a latest high technology long distance communication tool. It’s very intended, isn’t it?
