Projections washing across a facade in Mainz after dark, the light show over Napoleon's tomb in Paris, lantern festivals, a church in Regensburg lit for Christmas. Art turns cities into something else.

The Monet room you stand inside while it moves around you, the Dark Matter kind of digital maze, the exhibits that trade the frame for the whole room. Bring the person who swears they hate museums.me to hear.

A concert in a castle courtyard, an orchestra in a Roman amphitheater, the Venice Carnival playing out over the water. When where you sit is as much the point as what you came to hear.
