Wave Wrapper and LEDs: Question ???

While playing with the Wwrap circuit (Thierry Rochebois design) I got to
thinking about how the stages work... Each stage operates over a small
voltage range, and beyond that the amplitude "breaks out" and becomes
the input to the suceeding stage.  This can be repeated many times to
allow multiple wraps.

I tried simulating this using back to back LEDs as the diodes. They have
a large voltage drop (true) but as a side effect they light up in
sequence as the input amplitude gets larger.

Does anyone have experience with LEDs as clipping devices. These are not
in a feedback loop here, they are just forward biased or not...

Is there any effect of photosensitivity of the LEDs. Do they form a
detector that could photon couple noise (ambient light etc) into the
circuit if they were exposed (like through a front panel...

OK I just like blinkey lights... allright ????
