Aerial advertising uses a variety of different mechanisms to create messages in the sky. Customers can write their message or figures on paper, which is a much smaller version of what they want to see in the sky. It is the computer program’s job to enlarge that message for the sky.

To simulate this experience, students will create code to command Hopper to enlarge a figure. The goal is for the drawing to be an exact replica of a figure drawn on paper, but at a larger scale.
