[Squeakland] OLPC pen trails for turtle graphics

[Simon Guest]

Hi,

I'm just about to start my own kids off on some OLPC Etoys
investigation, so I had a quick play, intending to make some turtle
style polygons.  It didn't work as I expected.

A simple script like this:

Repeat 2 times
    Star forward by 100
    Star turn by 90

did not leave an L shape trail as I expected, but a diagonal line from
the start to the finish position.

Is this how pen trails are supposed to work?  How do I draw a classic
polygon, where the start and finish positions are the same?
Currently no pen trail is left at all.

cheers,
Simon
