Apparently a laser light show — or, rather, a piece of “illumination art” — was projected onto the National Cathedral:

Last night, Hofstetter ran a series of glass plates through a 6,000-volt projector and said artisty things like “Light is hope, fire is energy. These colors mean hope and energy.”
The images projected on the cathedral “speak of unity and reconciliation . . . and human oneness,” said the Rev. Sam Lloyd, the cathedral’s dean.
In truth, the sight of the neo-Gothic cathedral swaddled in a phantasm of psychedelic lights was a little jarring, the way the Mona Lisa would look with a rainbow ‘fro wig. The whole concept seemed vaguely overwhelming, like those midnight planetarium laser shows of yore, only without the Pink Floyd soundtrack and all the reefer.

Ridiculous. Maybe they can bounce the next light show off some of district’s forthcoming Socialist Realist statuary?
