Questions

Did you have a good break?

Mostly. But I’m broken.

Lab

Should we work in the interactions pane or the definitions pane?

I tend to prefer that you put your definitions in the definitions pane, and the individual actions (like (turtle-forward! tommy 10)) in the interactions pane.

What should postconditions for a turtle procedure look like?

You should describe what has been drawn.

You should describe the new position and orientation of the turtle.

Why isn’t the brush size working?

I don’t know.

What’s the writeup?

4i

This is class 33
