Pulfrich - Ganzflicker experience page

left|right hemifield

RGBA hexadecimal, where A sets modulation depth; e.g.,
 
ffffff7f: grayscale flicker at moderate modulation depth
ffffffff: grayscale flicker at maximum modulation depth
ff0000ff: red flicker at maximum modulation depth
00ff001f: green flicker at shallow modulation depth

Ganzflicker is inspired by pseudo-hallucination research of Reshanne Reeder
and may be combined with The vOICe sound re-visualization videos showing in
your peripheral vision on another monitor

The experimental Pulfrich hemifield effect might induce a phase difference
between the brain's hemispheres due to brightness or color dependent neural
delays, but you can also explicitly set an inter-hemifield phase difference

Note: you can also apply settings directly via URL query parameters, e.g.
for setting frequency, phase difference and (hemifield) color
