Not really an illusion, though – it’s just a way of delivering animation frames isn’t it?

Ah, point taken , IVAN3MAN. Yes it is intriguing and clever. Is it really an old painting/photo/vase or whatever? Thanks for pointing it out.

Actually it reminds me of a time when at school nearly 60 years ago, when I came to my fellow class-mates, and I think some slightly older fellow students, and they had been looking at a drawing, (pencil, as I remember), of an Indian Chief. I only had a brief glance at it before it was rolled-up, but I thought (imagined?) that it was somewhat more than bawdy.

To this day though, I have no idea what it really was, that was “hidden”. If anything. But I can’t imagine what they would have been so interested in, being normal kids, growing-up.

Maybe it is a case of xxxxxdoilia.

Ivan.

In what way is this an “illusion”, and not just a clever hack?
Unless you consider something like a flip-book animation to be
an illusion of motion, this seems like just a cute way to deliver
a sequence of images that behave exactly as you would expect.

Or is it a case of “Dolphindoilia”?

What Dolphins? Or am I looking at a different picture?

Is it because I’m Down Under, and all the dolphins are out of the water?

Just thought I’d ask.

A little spendy for what it is, but I got on special at a local store.

Bouncing tiger? Where’s Calvin?

Is this really bad to post something that is very off topic again? Sorry, but if you’re a science geek check out the newest documentary from PBS. “The Atom Smashers”(!). It’s about Fermilab trying to find the Higgs.

Leon Lederman is a character in it people (the coolest modern day scientist on the planet-hands down- and has the best sense of humor).

[...] This has seriously got to be one of the coolest optical illusions I’ve ever seen on the web. Drag the lines slowly for the best results. Link via Bad Astronomy. [...]

Wow. The optical illusion has turned into an HTML lesson

That illusion is obviously a bouncing tigger!

IVAN3MAN said:
The required syntax code is: *img src=”yourURL.com/image.jpg” alt=”image name here”/*

Hmm…let’s try an experiment:

When I submit, I’ll find out whether IVAN3MAN really needed to replace the angle brackets with asterisks, or could have used the “<” and “>” entities instead.

Autumn, I had another look and, yes, there are nine dolphins (my mind must have been distracted earlier), and also there appears to be at least one fish in the mouth of the dolphin at the top and to the right of that picture.

quasidog, this is how that emoticon, that you had attempted, is done: colon “:” and upper-case “P”, e.g., , and voilà…

Micheal L, I’ve had similar problems with an over-sensitive touch-pad on my note-book computer. Try using Firefox 3.0.3 browser; its security feature can be set so that it will block any submission with a security warning until you press the “confirm” button. Alternatively, write out your comment on WordPad first, then, when you have finished writing/proofreading, copy and paste your written comment into the comment box and then, after one final spell-check (with Google toolbar), submit the bloody comment. Either of those two options will save you a lot of frustration.

ERRATUM: Magnus, if you want to post an image here, you have to use the HTML tags: "<" and ">". The required syntax code is: *img src="yourURL.com/image.jpg" alt="image name here"/* N.B. Replace the * with " < " at the front, and " > " at the end. Also, you must enclose the "URL.com/image.jpg" and "image name" within quotation marks, and no space after the "<" tag nor before the ">" tag . It is not necessary to include alt="image name here" and can be omitted; however, in case the image fails to load due to server/bandwidth problems, it does serve the purpose of informing the viewer what he/she should be seeing. I trust this is clear now.

Or agnnus could just cut and paste the image source into the post and let the BA spam filter hold it til it’s checked out by the BA

If you are really old (like me) you might have had a cardboard zoopraxiscope as a kid. Much less capital investment than a computer! Self-powered.

Mus, I see your… er… 8 dolphins.

Michael, I wonder how a cat/dog would react to that dragon illusion? Probably will spook them!
