Gravitram 4 at the Museum of Science and Industry in Louisville, Kentucky 1986
The design of this Gravitram signals a departure from the 1" steel balls used in the previous 3 sculptures. Now a larger, bolder ball is introduced, requiring the rethinking of many of the engineering challenges of the structure. Here for the first time a hard plastic 2" ball is used, and the familiar bowl is gone. Gravitram 4 introduces also many additional features not seen in the first 3 sculptures. The most significant of these is a chaotic pendulum powered by the moving balls and seen at rest in the left picture and in partial movement in the stereo pictures on the right. The outside size of this Gravitram is the same as Gravitram 3, it is 60" x 40" x 84" and it is enclosed in a glass case with internal illumination.
