Collect all open windows to one space

I love using Space, especially after replacing an aging 15" PowerBook (more than 4 years old) with a brand new MacBook with a relatively small 13" screen.  However, sometimes I found my application windows are all over the four spaces I opened and I need a quick way to move them into one space.

Here is the trick: Enter space, press c, all windows will be collected into the first space.  Press shift+c to watch the slow motion.  Enjoy!
