Now on ScienceBlogs: Dr. Rolando Arafiles: Antivaccine rhetoric, colloidal silver for the flu, and Morgellons disease
An exploration of the serious/fun/ridiculous - past/present/future of the brain and the science that loves it.
The Omnibrain is a psychology graduate student at an online university. He hopes that the three weeks and $29.95 that he is spending on his Ph.D. will get him a job at a Tier 1 research university. Do online universities have postdocs? Ok...just kidding, The Omnibrain is a real graduate student at a real school somewhere in the continental United States - or maybe Europe.

I've entitled this illusion 'The Purple Nurple' Exciting eh? I haven't actually seen this particular one before today so I thought I'd throw it up.... so here it is:
I've finally figured out where the heck this illusion has come from! It is actually called "Sea Sickness" and is by Walt Anthony.

Corrected.

Interesting that it only works when I don't look at it. As soon as I focus on it, especially the center, it stops vibrating.

If you hold your eyes still it stops moving, but if you flick your eyes about the page, it starts up again.

I only see it shift a little when I move my focus to and from the very center. I assume it's supposed to be one of those that constantly moves?

...that illusion is making my eyes itch. x_x

It only moves a little bit for me... but thats enough.
Makes me feel like a bad night in Tijauna.

Er... The Purple Nurple is the name of a gay club themed area on Furrymuck :>
I cant get it to work. It looks perfectly stable to me, wherever I point my eyes and however fast or slow I move them.

Cool illusion! Interesting that it stops when eyes are fixed in the middle.
Try to circle your eyes around the outermost layer of diamonds.

About the ugliest illusion I've seen yet. The garish colors must have something to do with the minor illusion. Color fatigue? I only noticed some "movement" when I moved my eyes across an outer area, such as around the circle of diamonds.
Why not have a ranking of illusions by: 1) perceived movement, 2) aesthetics, 3) color fatigue, and 4) patterns?

Very cool illusion!

I'm w/o my printer at the moment. Does it work the same color printed onto paper?
Posted by: BJ | December 30, 2007 6:13 PM
Sorry. It just sits there doing nothing. I've tried everything. Hmmmmm...
Posted by: Myqlkc | December 31, 2007 11:52 PM
If you open up your eyes wide (as if beeing extremely surprised) and look at it, it appears frozen for me.
Posted by: Jürgen | January 3, 2008 3:46 AM
it breathes!
giving away my "age/generation" --- it has an LSD-like effect...
not that i would know what that might actually be... ; )
Posted by: mike/ | January 3, 2008 8:10 PM
I get no effect whatsoever. I gather it is supposed to move in some fashion. I can't even get it to muster a tic.

Joekdoe: do you sit around watching Simpsons episodes and then pronounce each and every one of them "Worst. Episode. Ever."?
Yeesh.

Apparently this bit of history is "old news"? Unlike... everything else in history???

So many of you discussed your love for vintage clothing in the comments section of my previous posts, which made me smile from ear to ear because I love history. I think it’s important to understand how fashion has evolved and why it has changed over the years. So I am going to go through the decades starting with the 1920s through 1990 and talk about what was popular in the world of fashion. We’re trying something new this week.
