Hi Elias,

Ehm. i didn't actualy. so i' googled and did get a little wiser..

Your code may work in shoes..
But as I am trying to write in green_shoes I got the following error.
----------------
naamloos.rb:7:in `block in <main>': undefined method `choose' for 
#[Shoes::ListB
ox:0x33b5530] (NoMethodError)
         from 
c:/ruby192/lib/ruby/gems/1.9.1/gems/green_shoes-0.176.0/lib/shoes/m
ain.rb:77:in `instance_eval'
         from 
c:/ruby192/lib/ruby/gems/1.9.1/gems/green_shoes-0.176.0/lib/shoes/m
ain.rb:77:in `app'
         from naamloos.rb:2:in `<main>'
-------------------------------------------
I have seen similar errors all morning.
Maybe those methods aren't implemented yet in green_shoes.

Yeah, I'll try to write them in this weekend. :)

Done.
Try out green_shoes 0.179.0 : http://rubygems.org/gems/green_shoes

Hope it works well. :)
