The Mac OS package comes with a samples folder in the dmg, this folder
contains many things, including simple-bounce.rb, and here's where it
goes wrong...
@icon = image "../static/shoes-icon.png", :left => 100, :top => 100 do
There is no static folder in the dmg, or if there is, it's invisible
and doesn't come along for the ride when typical mac user copies the
samples folder off the dmg image. Maybe it'd be best to code in a http
url to the image, or to create your own mozilla-style 'protocol' for
stuff built in to shoes... shoes://icon.png?
