Few projects have galvanized the imagination of San Antonians like the nine spectacular works of public art highlighting the "art reach" of the San Antonio River Walk. The River Spectacular features dramatic color photographs by Mark Menjivar exploring the array of painting, sculpture, sound and light along the 1.3 mile Urban Segment of the winding Museum Reach north of downtown. The artworks, completed in 2009, were commissioned by the San Antonio River Foundation. Media range from fiber optic cement to glimmering pieces of dichroic acrylic to the sounds of birds calling.
