Projection Pen / Pen

Sometimes, when you are walking, having a cup of tea or on the bus, suddenly, you have a sudden inspiration with a very good idea, or want to record things. But at most of the time, you may lose your ideas forever without pens and paper. This design can solve your problems. This projection pen can record your path of the pen movement, so you can write or paint anything you want in anywhere, the wall, table, or even your clothes. Then you can use the pen to project what you have recorded in any place, though this way, you can display your thoughts and feelings to others, and communicate with others.
