Mike,
That was the first stereogram I've looked at in the past few days (I've been looking at several) that popped out ... instead of went in ... and I didn't have to hold my finger in front of it to "keep" the image. Must have something to do with my near-sightedness and the "CONVERGING" option you mentioned http://www.talkgraphics.com/images/smilies/cool.gif
