    Re: Variants of the Bris
    From: Greg Rudzinski
    Date: 2009 Jun 24, 09:45 -0700

    Trials of the Butterfly Bris attached to sunglasses has shown
    excessive and variable distortion of the sun image when nodding the
    head. This is perhaps caused by curvature of the sunglass lens. Better
    observations were made with the Bris held well out in front of the
    sunglasses.

    a plethora of sun images in three separate fields (left,center,right). I find 
    it too busy for my visual taste though and prefer the Butterfly Bris variant 
    seen here attached to a pair of sunglasses using a rubber band. This 
    arrangement works quite well. Use two pair of dark sunglasses (one over the 
    other) to view the bright primary sun images and a single pair of medium 
    sunglasses for dim secondary sun images.
