Saturday Nightcap

Look at this fascinating artistic coffee table designed by artist Bruce Shapiro.

Underneath the base that the sand is on is a rotating arm, and on the arm is a sliding carriage that has the magnet that moves the ball creating the san sculptures.

The rotating arm and sliding carriage are operated by stepper motors that are in turn controlled by CNC software.

Apparently, you can download the CNC files for various patterns and routines.
