In a series of paintings on cities of the future, McCall envisions new technologies that will permit the construction of residential megastructures, allowing people to live in fanciful apartment towers hundreds of stories tall.

Advances in technology will also allow us to explore the rich and colorful world that lies under the sea. Here two large submersible bases launch smaller craft adapted to a variety of uses, including agriculture, surveying, archeology, and recreation.

An airbus transports citizens to this graceful urban mall surrounded by a series of parks, fountains, and canals. The painting was commissioned by Melvin Simon and Associates, Inc., a major builder of shopping malls.

For a pavilion at Disney's EPCOT Center in Florida, McCall was asked to convey the scope of human history on Earth. "It represents the flow of civilization from the past into the present, and on into the future," says McCall. The artist added a personal touch by including members of his own family in the painting. The brilliant wildflowers in the foreground were painted by McCall's wife, Louise, who is also an accomplished fine artist. (Courtesy The Disney Corporation.)

Innovations in construction and design will make even the bustling centers of our great cities into inviting places of great beauty.

Ingenuity and imagination will transform entertainment media as well as industry and commerce. Here a festive cavalcade of fanciful alien creatures parades across a giant multi-screen theater of the future.

Young and old enjoy a stroll along a tree-lined mall on a balmy moonlit evening. A gleaming pavilion filled with celebrating visitors is suspended above the parkway by yet-undiscovered antigravity technology.

A sleek cruise ship glides by an artificial island marina in a city design for the next century. Large-scale "ocean-going cities" such as the one depicted here are already on the drawing boards and scheduled to launch within the next ten years.

Solar power will provide much of the energy needed to power the cities of tomorrow. This "solar farm" in the southwestern desert uses advanced solar-cell technology to harvest radiation from the sun for transmission to urban areas by microwave and cable.

Properly used, human intelligence has the potential to free us from want and unnecessary toil, allowing us to enjoy our lives more. This light-hearted painting depicts an air cycle race in the Wyoming hills. In the background are vast "megatowers," massive structures made possible by new insights in physics and materials science.
