Named after an industrial programming language, this piece uses vacuum fluorescent displays like those found in a desk calculator. They are suspended from their wires inside the blue acrylic tubes.

The numbers jump and flash in unpredictable groupings.

The circuitry can be seen by turning the piece over and looking inside the base.

Each ladder step contains a 12 digit display made of glass.  I programmed a memory chip for each step that contains a sequence of randomly generated number groupings that change at unpredictable intervals.  I also designed the circuit to flicker the displays slightly to give the display some "energy".  This was done by slowing down the display multiplex circuit as it scans from one digit to the next.
