my entry for this contest: [link]
the previews are highlighted on mouse over. without the mouse over their opacity is 50%.
the 'contact us' link too, on the 'about' page.
the boxes on the 'mail' page also. but just the borders, and only when the person is typing something there.
the letter is supposed to be the 'Submit' button. it is also highlighted on mouse over.
i don't know about the logo...
