Thanks, Tim, I appreciate that. This is turning out to be one of my favorite shots as well.

Seems it doesn't work for me. :? Crossed eye... parallel view... or what ever... I always see as it is - a double photograph. Nikola, sometimes it helps to use some sort of barrier to block the confusing extra images. With crossed eye view, this is very easy: http://www.janrik.net/MiscSubj/2007/Leg...

Interesting links, Nikola. I can't quite figure out the pattern in the coffee beans. There are small spots of image that are exactly or almost exactly duplicated, but if you layer and shift in Photoshop you will see that duplication is restricted to only a few beans at a time. Apparently someone had...

You know this is funny. No not funny as in "ha-ha" but funny in as being unusual. When I visualize the large pair of seeds, they tend to stand out in 3D with really good relief but when I visualize the smaller pair at the bottom, they appear "concave," sort of like looking into a waspers nest. :smt...

Actually I did notice the difference in colour Rik, but thought it was on purpose for this excercise. I couldn't stand it. Through the miracles of Photoshop, the backgrounds are now identical. The colors of the seeds are still not identical. Closer I think, but not identical. But I have other thing...

I find the two smaller images much easier to visualize in stereo than the larger two at the top and yes I did have a bit of difficulty switching between the two. The blue background really makes it or them, easier to visualize also. Interesting. It's the opposite for me -- I prefer crossed eye to p...

Joan, there are a couple of possibilities. Something like 10% of people just don't perceive stereo, meaning that even with natural scenes they can't determine depth without moving their heads. It's surprisingly common, even among people who see fine with both eyes. The other 90% see stereo just fine...

Joan, try this: Take your hands off the keyboard and back slowly away from the monitor! Um, no, that's not really a threat, it just sounds like one. :roll: The real point is that the farther you back away from the monitor, the less your eyes will have to cross, to fuse the images. After you get them...

These belong to some small legume that grows as a weed along my back fence. I don't know exactly what it is, but it reminds me of a teeny tiny alfalfa plant with yellow flowers. Anyway, the seeds have always struck me as having interesting shapes and textures. I've never taken time to photograph the...

This is a really nice catch, Joan!

I'm proud to say that I did find the critter before looking at the answer, but only because you told me there was something to see.

And even then, it took a while!

Looks and sounds like one of the silk moths. There are several species with quite different appearance in the adults. I will be very interested to see what comes out of this thing! --Rik PS. You're right -- that vigorous rattling is a good sound. :) But I'd recommend keeping the cocoon in an unheate...

Ah! That explains why Google kept telling me about Euphorbia trigona , when I was asking about Ariocarpus . Despite many years of schooling, I have never tried to make sense of biology naming conventions. (Of course, most of my schooling was in math & engineering. :wink: ) And I have at least one fr...

Raul,

Another very nice picture. You have a talent for making white look great!

I see that the new username is showing up OK. ("Caronte" ---> "Raul G") Let me know if you need any more help.

No Alien 47 yet?

Give them time, Nikola, give them time. The graphics are coming along nicely already.

Of course, I am teasing you. It is only fair...

Mine is blue tagboard. If it doesn't hide enough stuff I use a pink sheet.

Thanks for posting, Wim. Very informative.
