Wish for screenshot feature

[Satoshi Asakawa]

_why and shoemakers,

I got a cool idea from the Shoes programming course of RubyLearning.org.

It's the screenshot feature like this:

Shoes.app do
  ball = oval 0, 0, 10
  animate{|i| ball.move i, i}
  timer 3 do
    screenshot './pic_in_3_sec.png'
  end
end

We can get the screenshot of Shoes canvas (meaning without window frame)
as the png format image data file named pic_in_3_sec.png on the current
directory! :-D

I don't know if it is feasible. It might be a stupid idea.
But, really wish! :)
