Collector of ideas

First of all I recommend to read the manual in which you will find the description of different functions and examples. For instance number 1 has a small notebook, I think it is the A5 format. The format is surely the same, only the colour of the covers is different. This person does the same and hands over. And this goes on and on. André Breton said that everything began just out of fun, but it finally turned out as extremely enriching.
