For this I made a 200x200 sized canvas with a black background. After adding the word "SPACE" I changed the background color to yellow, increased the size of the canvas to 300x300 then added the word "MORE".

Below you see the same image in 3 different sizes.

   I thought this was the coolest thing. Its like having a very flexible "Print Screen" button.
   It allows you to capture any image in any program including Web browsers.
