Lesson 29 Tasks
- When you see code that looks the same, put it in its own script.
 - Replace the removed tiles with a single call to the new script.
 - A benefit to code reuse is that you one place to make changes.
 - You can import existing images by dragging them to Etoys.
 - You script imported images just like any sketch.
 - It's good to use PNG or GIF images as they can have transparent parts.
 - You can trace over imported images by opening the paint canvas over them.
 - Use the turn toward tile to make one sketch face another sketch.
 - To move a sketch randomly, use the random tile to set both the x and y.

Trace the photo as a sketch and erase the original photo.  Make both 
sketches move at different rates, though have one chase the other.
