Daniel Mayer designed the luminous stained-glass murals as a rhythmic book-page sequence of fourteen monoprints that began with leaves from Arizona trees pressed into aluminum foil using an etching press. After inking the images to highlight their embossed lines and details, Mayer used a digital program to enlarge the “leaf prints” to the size needed for the murals.  The digital images were screen-printed, hand-painted and kiln fired on glass panels with permanent ceramic glazes. Each mural includes 28 laminated glass panels spanning 115 feet by 9 feet.  The artist worked closely with the PHX Sky Train design and construction team of HOK Architects, Gannett Fleming engineers, and the Hensel Phelps Construction Company to integrate the murals into the bridges. He collaborated with Franz Mayer (no relation) of Munich to produce the stained glass. Walters and Wolf installed the glass. Dinter designed the lighting in collaboration with the artist.​
