I think the attached image is a fitting tribute to Neil. It is the stained glass 'Space Window' in the National Cathedral, which was the site of today's ceremony. On July 21, 1974, Neil, Buzz Aldrin, and Michael Collins delivered a sample from the lunar Sea of Tranquility to the Cathedral for inclusion in the window. You can read more about the window on NASA's site.
