alice-teacher Probably an easy question

[Roger Crowe]

One additional note: one of my students came up with putting an additonal
object off camera *opposite* the wheeledrobot and had the head *Turn to
face* the object.  We even tinkered with the opacity of the object just in
case it would at some point come into view.  I thought it was an
interesting work around.
