I always see the old woman first and have to look for the young woman.

The classic Orbison illusion:
It's a bit boring, but I like it as it's related to the work I do:

I dunny get the Orbison one, it looks like a square in front of some lines. What's the illusion?

Glenh - what work do you do?

I like the sausage finger one. Keeps me occupied for hours.

Here's another version of the same illusion.

Everyone like this colour adaptation one too (you need to look at the cross for 30s or so without moving your eyes):

Like the last one, not sure what is going on in the first 2.

In the first the outline of the image is rectangular (an the red thing square), but doesn't look it.
In the second, the red lines are straight, but look bent.

These are good too (there is no movement in this image):

Flying Christopher Walken:

And the running spirals:

i can only see the number (25) in the first circle.....

but then, i'm colour blind....

Lies.

Is she spinning clockwise or anti-clockwise? Are you sure?

that wife is spinning clockwise! i can't see it go the other way no matter how hard i look at it.

Edit: can see it now, its all to do with the shadow and the foot. that is freaky....

I just tried to get up and fell over.

I still can't see the waterfall donald!

that wife is spinning clockwise! i can't see it go the other way no matter how hard i look at it.

Read the text under her and she seems to change direction 😕 for me anyway.

aye, its the second foot shadow that was getting me.

I'm off for a lie down.

grahams - now that is just wrong, i'm now very confused, have you swapped that image in the last 5 mins to make her go the other way?

That spinning woman one is awesome i looked at it for 5min and clockwise couldn't make it go anti clockwise, then looked away briefly and its anti clockwise, i need a lie down 🙂

Don't have a scan of it but my bank account is a great optical illusion...at first glance on pay day I have money...blink and it's all gone...one minute it's there and the next it's not...

I'm not sure I really understand that rotating woman one.
It's certainly not a visual illusion in the true sense.

Anyway, surely the direction is entirely dependent on whether you consider your view point to be from above or below?

There are no numbers in the rest of them....

😯

Your supposed to look at the woman or it would say which way is the shadow spinning. No matter how I look at it it's always clockwise.

can't make her spin anticlockwise no matter how hard i try

i'm struggling with the waterfall as well

I can "make" the woman spin the other way, but I have to really concentrate, and that makes my head hurt

well bugger me, it only bloody works

stair at the shadow for a while, at first it looks like she is oscillating but then all of a sudden she's going the other way

momentary blink and she's back to clockwise again

😆

I think I'm concentrating on the shadows nipple too much to get the full effect.

Oh yeah, it does work!

By playing with the gif in a media player (stopping and starting it) I can make it appear to rotate both ways 😯

They are numbers 25,29,45,56,6,8. Hope that helps. Oh and the spinny things hold your mouse over them and they stop or slow down. THe Spinning woman thing is strange tho.

I have printed out that dragon and plan to make it tomorrow morning when I'm in the office on my own.

or just look at the centre or don't move your eyes atall

There must be something wrong with me as I can only see her going anti clockwise.

well you know what they say about 'creative types' lowey

[i]or just look at the centre or don't move your eyes atall [/i]

That worked briefly for about 2 seconds and thought "wow she's going anti-clockwise" which then made my brain switch again and can't get her to do it any more.

i meant the spinney spiral thing, but i got a similar brain **** thing with the woman

at first the spinny woman ws going anti-clockwise. the GF saw her going clockwise. then read the spiel about it on the link and thought "how true", but later read something on wiki about the spinny woman and it said the left/right brain thing was bull....

the spinning woman is crazy! But i think glenh's are best especially the one where the colour dots magically disappear. Explain yourself you sorcerer!

the colour dots thing is the brain having too little time to react to the colour change.

the grey background is made up of RED+BLUE+GREEN and the Purple of RED+BLUE

When you take away the purple and leave the grey the brain just thinks you've taken out RED and BLUE and left GREEN

the centre section of the eye is more sensitive to colour and has more densely packed light sensors so when you follow the dot round with your eyes you see purple and grey not green

the blue and green are the same colour (I checked! twice).

which square is darker A or B ?
[img] [/img]

(answer: neither)

What... is A

And the woman is only spinning anit-clockwise. No was can she turn teh other way, i looked till my eyes hurt!

That blue and green one above as well! There different, surely?

LOL. You must look again young glasshopper 🙂

that 2 lines are straight, not bent is rubbish. The lines are wider at the top than the bottom, i've just measured them. Therefore have to bend in towards the bottom. Spinny woman thing, always clockwise for me, and surely the colours are different ( green and blue)

I think you are confusing "straight" with "parallel". They are not parallel, but they are straight even though they appear to bulge in the middle.

surely the colours are different ( green and blue)

Zoom in and you will see that the blue ones are green with a blue outline.

apparently you're left brained and will is right brained. Or is it vice versa? The good news is that between you, you have a whole brain 😀

Thank god for that. Which side says ' go for it, you'll make it ', and which says ' c'mon, who you kidding.. mortgage, car, job etc' ??
