Gallery of Logo
Nanoworlds
Logo Nanoworlds
are small online-games that are supposed to encourage thinking about
programming concepts. In this gallery you find some
prototype
nanoworlds that focus on the concept "calling a procedure is delegating
a task to another actor". The player can define up
to three procedures, each one attached to one type of turtle.
These nanoworlds will be a part of the future "Museum of
Informatics" of the University of Münster (Germany).
