I really like the continuation that is used in this Pink Floyd poster. The way the white beam seams to pass through the triangle and become a rainbow is really cool. It's really just a white line, a triangle, and a few colorful lines stacked on top of eachother. It's very interesting how such simple steps can be so interesting. 

I used a paint app on my computer to draw a giraffe, and then copied and pasted it a few times to show similarity. It looks as if there is a herd of giraffe when they're all next to eachother. Also, the giraffes each appear to be looking over their shoulder. The intention is continuation. The viewer should follow the giraffes' eyes to see what they're all looking at. It draws the viewer's attention to the butterfly in the corner.
