I too entertained the notion that binocular vision might enhance the effect. When I first viewed this display, about a year ago, I had good binocular vision, and the apparent movement was quite prominent for me. Now, however, it is much more subtle, perhaps because of my loss of good binocular vision following the death of neurons in my left, anterior, optic nerve (caused by an ischemic event a few months ago). I can still see some movement when I view the display with only one eye, as long it is my right eye. When I use only my bad (left) eye, I see no movement, and peripheral parts of the display are blurred.

Well, I tried it w/o my glasses (and I have an astigmatism in one eye and 20/200 vision in the other eye) and still saw the illusion. However, when I closed one eye and looked at it, the illusion went away. Anyone else notice that it seems to be binocular? Or is it just me? --- You are currently subscribed to tips as: [EMAIL PROTECTED] To unsubscribe send a blank email to [EMAIL PROTECTED]
