    but No.


    Just beans for me...

    How many of you can focus easily to see the 3-D image embedded in a stereoscopic image? Some people seem to have great difficulty.

    Generally I can.

    I did make a few autostereograms a long time ago (forty years?) on an
    Atari ST microcomputer using software described in a paper from Bradford University(?), UK. The printed paper arrived in the post - it was before
    the Internet became ubiquitous.

    The image size, image resolution, viewing distance, pattern repetition
    distance and pixel offset need to be such that it is comfortable for a
    viewer to see the embedded image. The viewer needs two reasonably
    functioning eyes too.

    Web based autostereograms probably should have a recommended screen size / resolution and viewing distance. What works on a big screen isn't going to comfortably work on a phone's small screen.

    The idea behind the internet was a good thing.
    Having access to that theoretically invaluable resource everywhere is a
    good thing.
    That requires mobility of the access points.

    If you're not happy that 2+2+2 is 6, one of your 2s is wrong.

    Yep. That first 2 is the screensize, in inches, and that second 2
    is the number of characters you might be able to type accurately
    on a microscopic keyboard.

    But hey, you do you.
