Hi list -- I found this demo on http://planetsqueak.joyful.com/ -- a  
very nice intro to developing in Squeak. Stephan Wessels has  
obviously put a lot of work into this. Demo can be found at http:// 
squeak.preeminent.org/tut2007/html/index.html .

Thank you Stephan -- I'm having lots of fun with this.

Steve
