         | work?

       | 9-volt battery to your drawing at a certain point and a bulb or
       | LED that you 've taped to your drawing lights up. Maybe you'd
       | supply prefabricated stickers that contain logic gates that you
       | stick to the paper where you need a gate.

       | The Dutch childrens magazine Donald Duck included a DIY cardboard
       | 3 bit computer in four editions in 1980. It was powered by a
       | marble and gravity and it included QA cards, like "What shall we
       | eat? followed by three questions (hungry? Want sweet? etc) and
       | then on the back of the cards there were eight answers. You set
       | the switches to left or right, put in the marble at the top and
       | looked up the answer corresponding to the place where the marble
       | appeared.

       | I was seven years old and at that moment I decided I wanted to
       | become a computer scientist. It determined my life.

       | I assume that the kind of things you make when coloring are very
