This weekend at the National Cathedral was an event called "Lighting to Unite."
Description of the event from the website: For three memorable nights in May, Swiss lighting artist Gerry Hofstetter brings his artistry to Washington National Cathedral for a spectacular exterior illumination of the south and west sides, in celebration of the Cathedral’s centennial. Numerous vivid images will be projected directly on the Cathedral sunset to midnight on Friday, Saturday, and Sunday, illustrating its mission of reconciliation, spotlighting its role as a spiritual beacon for the nation, and proclaiming hope for all humankind.
It was pretty neat! I took a bunch of pictures, but these were the best...
