I just finished a class project in which I created a custom
morph, with etoys support (custom tile selectors), and connected
it to an external USB port via FFI and a vendor library. The
project was a Gauge Morph, to which a tile script was attached
that read a new temperature from the usb port on each morph

The code is at http://www.squeaksource.com/gauge.html .  I tried
to well-comment the complex parts (like how to add custom tile
selectors to custom morphs)

A demo project is at
http://www.public.asu.edu/~mtfulmer/GaugeProject.002.pr . You
will need to load the mcz package first
