Hi,
I am new to Squeak and Smalltalk. After reading a few tutorials I am very intrigued and impressed. Brief background for me: I am a mathematician, I am fairly skilled in Python, and I have worked at to varying degrees with C, C++, Java, Pascal, Basic, Fortran, Javascript, Ruby, R, and Mathematica.
I am homeschooling my daughter, who is 9. She is quite proficient at Scratch. A week ago I decided to give her a very brief tour of other programming languages by having her write a "Hello Pythagoras" program in each language. This program should print "Hello Pythagoras" somehow, and then ask the user for two inputs (call them A and B). It should then print sqrt(a^2 + b^2).
For her third language she chose Squeak, since she knew that Scratch was written in it. I would like to have her write the "Hello Pythagoras" program using Morphic objects, in a visually appealing way. So far I have had some trouble finding a tutorial that covers relevant information. I am sure I can figure this out by poking around long enough but if anyone has a pointer to documentation that might help, or a similar example, that would be great and much appreciated.
Here is how to do it in Etoys (using the Squeakland version from http://squeakland.org/ ):

Took maybe 10 minutes, and that's including the graphical display of the triangle :)
