Spiral illusion
The below image has an optical illusion. Can you spot it?
Believe it or not - and I didn't - the blue and the green are the same colour. I had to zoom in in Photoshop to prove it to myself. There's a close-up here.
Looking again at the full-size image, I can just pick up a green tinge at the edge of the upper-left blue, but that's all. Impressive. I'd be interested to see a writeup of it at Illusion Sciences. Via Richard Wiseman.
Spinning girl optical illusion
One of the most impressive optical illusions I've seen in a while. Which way is she rotating? She started off clockwise for me, but is now firmly anti-clockwise and won't change back for more than a second or two. I managed it by looking at the edge of the screen, rather than concentrating on her shadow, but ymmv...
Update: Re-reading the above, I see I didn't really express how amazing this illusion is. Usually with 'switching' illusions I can see how it works - that is, which part of my visual system is getting confused, and how the image is constructed so as to create the effect - but this one's a mystery to me. It's completely unintuitive. I haven't had a good dig around the site yet; I got stuck on this one and haven't progressed further. Anybody?
Colour Illusion
This has to be one of the best optical illusions I've seen. Even when you know what's coming, it's still a shock. Via BoingBoing.
Hello!
Hey, thanks for coming! I'm Andrew, and this is where my headthinks come to breed. They often dance around humanism, photography and general wonderments, but there's dabblage aplenty.
Do feel free to email me - I get lonely:
Your hair looks swish, by the way - have you done something new?
