Putting books on my devices mean purpose through message.
I enjoy reading and writing on my iPhone, laptop, desktop and iPad.
I still enjoy pen and paper to read, write and draw and to do mathematics.
There is still something very liberating about pen and ink on paper.
I also think better and configure better on paper with mathematics.
Yet, photography enhances and makes Wallpaper a creative practice on my devices: especially when I do it myself (apps are fun too).
