Today I stumbled across an interesting website:  The Million Dollar Homepage
What a great idea!  This site creator made a web advertising space that was 1,000 pixels square and sold each pixel for $1.  So to have a 10×10 spot (smaller than the size of my tiny little icon next to my page up there in the browser) you had to pay $100.  Then to purchase larger pixel areas you just add another $100 for each 10×10 square.  Well with 1,000,000 available pixels selling for $1 each the total value of that small single page is one million dollars.  Such a simple idea, so easy to create!  And now the creator is a millionaire with very little effort applied.  Genius!
