  • Project Description

    Triangle Twist is part of the branch of kinetic sculpture known as rolling ball sculpture. One-inch glass marbles travel on two tracks and go through dips, curves, loops and spirals to entertain the viewer and highlight the fun and fascinating motion of mechanical objects. Tools used include a Miller Maxstar 150 STH, various pliers, Vic Grips and pieces of pipe to bend things around, a band saw, drill and Dremel with cutoff wheels and buffing wheels.

    Build Process

    This project was conceived and built over a period of approximately ten days. All formed pieces were bent by hand. The basic design started only with the pyramid frame and the rest was decided as the project went along.

    Tools Used

    The sculpture is built entirely of stainless steel. The main track is 1/8" rod. The pyramid frame is 1/4" rod. Two pieces of stainless tubing were was used for the tipper-style track switch and starting gate, and some perforated stainless was used at one side of the switch to catch marbles and redirect them.
