What colour is this dress?

Many years ago I think I posted a picture on TG of a chessboard that illustrated the same phenomena as that shown in the video.

To check our earlier findings, I sat side by side yesterday with my daughter and we both looked at the image of the dress on my laptop, a few feet away and saw the two variants by looking at the same image under the same conditions. It really is an amazing thing.

Thanks for posting the video.

I used to look at the rotating grid of the old early warning radar station on our coast, when I was but a babe', and could make it rotate either way round simply by the power of my perception alone.. or because I let my brain get confused, which ever way you want to look at it [pun intended]

such things have facinated me ever since

I used to work for a defense company. I went with my boss - whose hearing was poor and had a hearing aid - to an on-site visit to a company near a radar installation on the south coast.

I saw the huge rotating radar and made a comment about it.

He said "Yes, I know, every time it rotates I can hear a blip in my ear!"
