Imagine, you live in the USA and your relatives live in other country… Well, you can use a lot of different devices from simple letter in usual envelop to high speed internet. Anyway you will miss them so much. I would like to suggest you one great idea.
For example when you will celebrate your birthday party, X-mass or Thanksgiving Day you will need your family so mush and I offer to make the huge screen on the wall in your living room and in the room of you relatives. Also the web cameras will be included into this device. So you will spend your holiday with your family. Of course it will be impossible to hug your mom but anyway it's very good device! I hope to have something like this at home soon!
