This is a creative design exercise, allowing participants to work together as a team in achieving an objective. As part of this exercise, delegates will get to choose a number of political cartoons and have an attempt at designing one. The design is just a pretext to get people talk to each other and share what they like or dislike. The cartoons provide an opportunity to laugh about serious stuff so the exercise is light hearted but can have significant value as people can easily end up discussing values, current affairs, ethical and political issues and of course politics.
Note that the emphasis of this exercise is in the descriptive design of a cartoon as opposed to the actual drawing or art. Most people are not skilled in drawing and forcing them to draw in this exercise might make them feel uncomfortable. This is why the drawing part is ignored (though of course you can optionally add it if it suits your training needs). However, there is no reason why people cannot come up with an idea for a political cartoon which this exercise captures.
