Sounds good. I have decided to create a "biography of a incomplete
project" as my "interactive art" project talking about how it started
with "physical etoys", went to "Etoys" then Pharo, but still is not
finished (in Spanish) I will be sharing the link with you.

The code to load a file is this:

x := ImageMorph new.
x image: (Form fromFileNamed: '/home/offray/Temp/myFile.png').
x openInWorld.
