When reading comics most of the attention goes to the drawings and the storyline. Yet there’s a lot of creativity behind the balloons used in a story. I’ll show a couple of examples below.
In the first example we see the normal use of balloons with a point to a character that indicates that this character speaks. When the balloon points to the character using several little circles it indicates that this is what the character is thinking. The text outside the balloons or in the rectangles is the voice of storyteller, the voice over.
To indicate shouting the creators of this comic use spiky edges on the balloons.
In this second example bold and italic are used to indicate shouting. In the bottom part of the page the characters of the other species speak a different language which is indicated by using a different font.
In this third and last example the red magical character in the story speaks a different language which is indicated by using a different edge.
