Pencil and notebook is a tool that is convenient for carrying around.
They were easy to drawing and always carry.
 
However, it was able to draw with only pencil only when you draw a picture with a note.
 
After the iPad happened, I carry a pen and pad eye instead of pencil and notebook.
With a good application, like a pencil in some cases, as watercolor some cases, it is possible to draw a picture such as oriental image in some cases.
 
It is possible to draw a picture with all one's might off the constraints of time and space.
 
In this project, can you show a picture drawn in iPad.
