Every Summer University should have a short introduction about AEGEE, since there are always many new members at a summer university.
To make it easier for you as organizers, the SUCT has made a nice and short AEGEE intro presentation! You can download it here:
AEGEE Introduction Kit (.zip) (3,5MB)
In the Kit you will find both the presentation (10 slides as images) as well as a Toolkit with different designs and the SU logo to make your very own SU introduction if you so wish.
