Perimeters

These provide variation within the perimeter advertising.
They therefore increase not only the attention paid by viewers,
but also the advertising revenues. Because the clips being
displayed alternate, the space can be used for many different
advertisements. This means there's also no need to change the
perimeter sections before each use. Furthermore, a Perimeter
opens up completely new dimensions for perimeter advertising,
namely the possibility of using animation and video to inspire
spectators.
