Week 5 - Style and expression. -- I completely restyled the comparison I made in week 2. Instead of arranging a bunch of borrowed or self-made photographs I drew all the pictures by hand (on the computer) in a childish way. This is because my handdrawing skills are not highly developed but also to show that a complicated concept can be presented in a "simple" way. I hope, however, that I did not oversimplify things and that the meaning is still clear.
