With the old Warped line video circuit the line generator and warp signal were on the same board with one unique warp signal generator per finger. In the new version the warp signal generation has been moved to a separate board. For each finger there are six different warp signal generation circuits that can be selected through a rotary switch. The rotary switch has a seventh position which I've left open for future use. The Z control voltage effects the warp signals so the line patterns also change as the finger moves closer to the screen. A DPDT switch swaps the comparator inputs which flips the line patterns vertically.
Examples of the new warped line effects:
