<div dir="ltr">Thanks, Ben! That is super helpful! For students who cannot learn to free fuse, this is a fantastic low tech method. I'm going to suggest it to my students.<div><br></div><div>For the demo, I wanted to use a random dot stereogram, to camouflage the image. I picked one from half of an artwork by Alphons Schilling, entitled "8 planes, 2 planes" (1973). I used the "2 planes" pair of a triple image work. In order to make it work in a mirror, I had to mirror flip the right eye image. I've then morphed it using PhotoShop onto your excellent figure, and made note of the revisions. I show it below, and have attached the file for anyone interested. </div><div><br></div><div><div><img src="cid:ii_k82i6qt12" alt="Stereo Demo Revised from Backus Vivid Vision [mirror stereo pair demo].png" width="422" height="562"><br></div></div><div><br></div><div>Best wishes,</div><div><br></div><div>Les</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Mar 21, 2020 at 3:49 PM Ben Backus <<a href="mailto:ben.backus@gmail.com">ben.backus@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr"><div>Les et al,<br></div><div>How about something like this?</div><div>Please use the attached powerpoint file any way you like.</div><div><br></div><div><br></div><div><div><img src="cid:ii_k822x5vr0" alt="image.png" width="421" height="559"><br><br></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sat, Mar 21, 2020 at 9:21 AM Lester Loschky <<a href="mailto:loschky@ksu.edu" target="_blank">loschky@ksu.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;border-left-color:rgb(204,204,204);padding-left:1ex"><div dir="ltr" class="gmail_attr">Thanks, Christopher!
