An early test marketing effort in the Comic Buyer’s Guide resulted in ten percent of the twenty seven 3-DVG buyers writing unsolicited letters. These early buyers received the Initiation model without any explanatory literature of how it worked.
"...As a person who’s interest in 3-D has been a life-long affair, I must say that I am absolutely flabbergasted that the effect of three dimensions can be achieved by such a simple device...I was able to achieve the desired 3-D effect on my very first try. Ever since, I have been pouring through old magazines, comic books, and sitting in front of the television, exploring an old territory in a totally new way. ...It is truly exciting to be among the first to experience this discovery."
Mike Johnson of Wheaton, IL
"Thanks for letting me in on the ground floor of this! What a marvel! Not only is this a great "parlour trick", but I suspect it has many possible applications with TV, interactive video, etc...." It is revolutionary, Its almost weird how simple the actual process is -it’s almost as if we were built to be able to see with this in the first place.
Blair Tarleton of Tarboro, NC
"…This unbelievable simple device creates an almost magical effect."
Harold H. Blesy of River Forest, IL
Comments from Photo-3D Mail List
"...I was at the convention in Atlanta, and was impressed with the 3-DVG, I still check certain images on the net and in magazines using my fingers to provide the similar effect to Ken's glasses. I learned the finger method from his great article in Stereo World magazine."
Lincoln Kamm, Maker of 3-D STUFF on Photo-3D Mail List (4/9/97)
"How's it work and how's it done? I am very sceptical of the whole thing. I have looked at a large framed photo and covered one eye over and this 'appears' to be 3D since the brain is trying to compensate, but the whole thing seems really 'suss'

"...What I am seeing is difficult to rationalise. The problem is that it _looks_like stereoscopic 3-D, and yet it can't be. I have two possible explanations, which are no doubt not news to you....Thank you in advance for any comments, advice and information.

"Thank you very much! I tried your experiment and was successful. I had a nice photograph of a forest that I selected and so the trees seemed to stand out quite nicely. I've been able to achieve a similar effect before by looking at on ordinary photograph through a single lens ...Very interesting. I'll add a link to your site soon. Thanks for the opportunity to try that out."
Professor William R. Marmie, Univ. of Guam (2/2/98)
"I just inserted [your] URL into the interesting Links page of my Web Book. I hope it was ok."
Peter K. Kaiser, Thomhill, Ontario (2/2/98)
"I am a high school student at Morgantown High School, and have recently had the opportunity to research a scientists work ... A friend and I have taken an interest in you and your 3-DVG invention, and have decided to base our project on them...."

"Well, I went to see the site_ check out the Dunkley effect. I was amazed! There is indeed an easy way to perceive "depth" in ordinary photos...."
Boris Starosta, member Photo-3D Mail List (2/4/98)
"...I believe that the effect is more likely [caused] from the bending of light rays at the inner edges of the pinholes (called diffraction) than it is from a prismatic effect of the lenses of the eye...Different wavelenghts bend different amounts, hence the chromatic depth effect"
David Lee, member Photo-3D Mail List (2/14/98)
"...The impression received by using Dunkley's technique is clearly "stereoscopic," in that you perceive depth in an otherwise flat photograph. Naturally it is an illusion. Given only one image, actual stereo cues do not exist....It is not unlike the view through "chromadepth" glasses but more interesting. I would encourage the various members of the P3d, who are knowledgeable with optics theory (Bercovitz and Abrahams come to mind), to have a look at Dunkley's site, because the effect is really quite interesting."
