Saw makes repeated cuts, in either direction, across each monitor on your system, in turn.  The bottom section falls away, with a crash, and another cut starts.  When it finishes a monitor, it remains blank.

• "Speed" adjusts how fast it cuts.
• "Cut Size" adjusts how big a section is cut at a time.
• You can adjust the cutting style for "Clean", "Chips" flying, glass "Cracks", or "Chips & Cracks."
• The annoying "Power Saw Sound" can be turned on and off independently.
