Snippet for demo - being in control moving the Pharo logo

As a general rule, people feel more confident about systems they can
control.  So I was thinking this might be a good snippet for demos to
give that sense of control.

"Evaluate one line at a time."
logo := ActiveWorld submorphs last.
logo center: ActiveWorld center.
logo top: 0.

Just applying the 0,1,many computing philosophy to demos.  Its better to provide more than one example, and two is enough to be many. Students should be able to guess that they might use #right:
So then they have developed a hypothesis, been proven right --> feel in control --> like Pharo.
