I got the gizmo working in color, with signals from my Aurora.
See the discussion and images in the British NBTV forum:

I'll post one picture here: the usual Dorothy. Note that the bottom of the picture is the bottom of her blue dress. It repeated at the top of the image, and the bottom of the picture is repeated at the top. The separator between pictures
is the green-magenta-red wavy line.
Of course this isn't the color forum, but this gizmo started out as black-and-red.
The original red LED is removed.
